A trait produced from two alleles that are alike is?
A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What would mating between a true breeding purple flowered pea plant and a true breeding white flowered pea plant produce?
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white
What kind of offspring will a homozygous tall plant and a homozygous short plant have?
Presuming tall is a dominant allele (the 2nd parent is heterozygous and "tall" is it's phenotype), then the square would be as follows: Let T be the dominant gene for tall, and thus every genotype containing this (TT, or Tt) would produce a tall plant. Let t be recessive, and in the absence of T (tt) causes a plant to be small. So the homozygous tall parent would be TT, and the heterozygous tall parent would be Tt. So now you just have to cross them. During meiosis, every gamete from the TT genotype would contain a T allele. However, for the Tt genotype, there is equal chance each gamete will contain EITHER a T or a t. So the square would be: xxTxxT TxTTxTT txTtxTt As you can see, 2 out of the 4 offspring have a Tt genotype (heterozygous), so this translates to a 1/2 fraction, or 50%. Ignore the Xs in the table- if i just used spaces then all the letters crunched up on top of each other when i pressed save...it was the best i could do...:S
If 240 plant offspring were produced from crossing two heterozygous plants how many would be homozygous?
Out of the 240 offspring, approximately 60 would be homozygous (25% of 240). This is because when two heterozygous plants are crossed (Aa x Aa), the Punnett square shows that 25% of the offspring will be homozygous dominant (AA), 50% will be heterozygous (Aa), and 25% will be homozygous recessive (aa).
Is The probability that a gamete produced by a pea plant heterozygous for stem height Tt will contain the recessive allele 100 percent?
false
A trait produced from two alleles that are alike is?
A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
What is probability that wto heterozygous parents would have an offspring that produced round seeds?
75% because the recessive and dominant genes are corresponding and in a Punnett square it takes over.
What describes the mating of organisms that have different homozygous alleles for a single trait?
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
How could a guinea pig breeder whether a rough-coated guinea pig is homozygous or heteorzygous for this trait?
A breeder could determine if a rough-coated guinea pig is homozygous or heterozygous by conducting a test mating. Breeding the rough-coated guinea pig with a smooth-coated guinea pig would show if the rough coat is dominant or recessive. If all the offspring have rough coats, it indicates the rough-coated guinea pig is homozygous for the trait. If both rough and smooth-coated offspring are produced, then the rough-coated guinea pig is heterozygous.
Can a white tiger and a normal bangel tiger mate if so what color is there cub?
Heterozygous - White gene carrier Homozygous - No white gene White tigers are not albinos and do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange. If two heterozygous tigers, or heterozygotes, breed on average 25% of their offspring will be white, 50% will be heterozygous orange (white gene carriers) and 25% will be homozygous orange, with no white genes. In the 1970s a pair of heterozygous orange tigers named Sashi and Ravi produced 13 cubs in Alipore Zoo, of which 3 were white. If two white tigers breed, 100% of their cubs will be homozygous white tigers. A tiger which is homozygous for the white gene may also be heterozygous or homozygous for many different genes. The question of whether a tiger is heterozygous (a heterozygote) or homozygous (a homozygote) depends on the context of which gene is being discussed. Inbreeding promotes homozygosity and has been used as a strategy to produce white tigers. (From Wikipedia)
What will be the ratio produced if Tt is crossed with tt?
The ratio produced would be 1:1 for heterozygous (Tt) offspring to homozygous recessive (tt) offspring. This is because the parent with genotype Tt will pass on one dominant allele (T) and one recessive allele (t) to its offspring, resulting in a 50% chance of either genotype in the offspring.
What genotype will be produced by a heterozygous?
The trait that would be expressed in a heterozygous genotype would be the dominant trait. If one allele is dominant then it will be expressed.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What organism has two different alleles for the same genetic trait?
homozygousHomozygousit means homozygous. if both alleles are recessive, the trait will be homozygous recessive. if both alleles are dominant, then the trait is homozygous dominant.An allele is a letter representing the alternative forms of a gene. In most cases, there will be a dominative allele, written as the capital letter (in this case, H, although the allele can be any letter), and there will be a recessive allele, written as the lowercase of the same letter as the dominative allele for that particular trait (h).These alleles can be homozygous (both the same, such as in a purebreed) eg HH or hh. On the other hand, they can also be heterozygous, meaning that the gene has one dominative allele, and one recessive allele. This is written as Hh.When something that is homozygous (either homozygous dominant, HH, or recessive, hh,) is bred with another homozygous that is the same, the offspring will have two identical alleles. For example, a plant that is homozygous with the alleles HH to produce the trait of red flowers, is pollinated by another plant, also homozygous HH for the trait of red flowers. The offspring will also have the homozygous alleles HH and will be a pure bred for red flowers.Such is the case for anything. If a gene has two alleles that are identical, it will be purebred for that particular trait produced by those alleles.homozygousIs homozygousl.homozygoushomozygous
