Most teachers will designate the dominant gene capital letter. In Mendel's experiment he crossed purebred Tall (T) with purebred short (t). He got all Tall plants as a result. Tall purebreed genotype is TT and the resulting generation was all tall by heterozygous with a genotype of Tt.
What else can I help you with?
Mendel crossed a purebred tall plant with a purebred short plant. What was the phenotype of the f1 generation?
The phenotype of the F1 generation was all tall.
What is the genotype for a homozygous tall plant?
For example, if the tall plant stand for T, the genotypes are: TT tt
How do dominant and recessive alleles affect an offsprings phenotype?
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
What must be true for a cross between a tall plant and a short plant to produce any short plants?
Both the tall plant and short plant must be heterozygous for the height trait, meaning they each carry one dominant and one recessive allele. When they produce offspring, there is a 25% chance of obtaining a short plant by inheriting two recessive alleles for the height trait.
What are the geneotypes of a homozygous and a heterozygous tall pea plant?
The word genotypes is in reference to the alleles an individual receives at fertilization. Lets say that the allele/gene/trait, genotype for the Tall plant is T and dominate and the allele/gene/trait genotype for the short plant is t and recessive. If the genotype is an homozygous allele/gene/trait has two dominate alleles/genes/traits seen as two capital letters ex: dominate tall=TT or if the genotype is homozygous with two recessive alleles/genes/traits it will have two lower case letters ex: short=tt. If the genotype is heterozygous is a Tall plant that means the allele/gene/trait will have one dominate T=Tall and one recessive t=short and it will look like this Tt and with this genotype a Tall plant will be produce "T", even though that plant will still carry an allele/gene/trait for shortness "t". Tips: homozygous [Gk.homo means same and zygous means balance] & heterozygous [Gk.hetero means different and zygous means balance]
What is the combination of alleles in purebred short pea plants?
Two alleles for tall stems.
Mendel crossed a purebred tall plant with a purebred short plant. What was the phenotype of the f1 generation?
The phenotype of the F1 generation was all tall.
Are all tall peas always purebred for tallness?
No, not all tall pea plants are purebred for tallness. In Mendel's experiments with pea plants, tallness is a dominant trait, but if a tall plant is heterozygous (having one allele for tallness and one for shortness), it can produce offspring that are either tall or short. Only plants that are homozygous for the tall trait (having two alleles for tallness) will consistently produce tall offspring. Thus, genetic testing or breeding records are needed to determine if a tall pea plant is purebred.
What does an alleles for a hybrid tall pea represent?
An allele for tall in a hybrid pea plant represents the gene that codes for the trait of tall height. In the case of a hybrid plant, there are two alleles for height, one inherited from each parent. If both alleles are for tall height (TT or Tt), the plant will exhibit the tall trait.
Is a purebred pea plant small?
If the pea plant has the genetic to be small in the homozygous state, then it will be and conversely so. One of Mendel's experiments was to cross the purebred tall with the purebred small to see which trait was dominant. The allele for tallness is dominant in the pea plant,.
WHAT DO THE LETTERS ON INSIDE OF THE PUNNET SQUARE STAND FOR?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnets square stand for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnet square stands for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
How dominant or recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
What is a pea plant with two tall genes said to be?
A pea plant with two tall genes is said to be homozygous for the tall trait, specifically represented as "TT." In genetics, homozygous means that the organism has two identical alleles for a particular trait. In this case, the plant will consistently express the tall phenotype when bred, as both alleles contribute to that characteristic.
The alleles for a hybrid tall pea plant are represented as?
The alleles for a hybrid tall pea plant are represented as Tt, where "T" is the dominant allele for tallness and "t" is the recessive allele for shortness. In this case, the plant has one allele for tallness and one for shortness, resulting in the tall phenotype due to the dominance of the "T" allele.
When a plant has two dominate alleles for tall stems its alleles are written as what?
(T,T) if t is the letter used for that allele capital letters are used for dominant alleles and lowercase is for recessive.
