How is the genetic material of a parent inherited by offspring in sexual reproduction?
The most common answer to this question is heredity.
State the conclusions reached by mendel in his work on the inheritance of characteristics?
- Some "alleles" (hereditary traits) are dominant, and others are recessive. - If a pure dominant trait is bred with a recessive trait, their offspring will show 75% presence of the dominant trait, and 25% presence of the recessive trait in the F1 (first filial) generation. - If a plant with a dominant trait from the F1 generation (carrier, heterozygous dominant) is bred with a plant that shows a recessive trait, their offspring will display at 50/50 probability of dominance versus recessiveness. Thus, alleles expressing a particular trait via dominance/recessiveness, in the case of the pea plants, take the form of two alleles that combine to express a particular version. This later has been shown to be homozygous dominance/recessiveness, or heterozygous dominance.
Do you get held back in 6th grade if you get 2 F's in science?
That's usually up to the parents or teacher, getting f's in the first place is bad. But I think getting 3 or more f's get yah held back.
What would happen if you cross the offspring of two pink roses?
When a red flower crosses with a white flower, it can create a pink flower. Why? Because of incomplete dominance. Incomplete dominance is when the heterozygous phenotype(offspring) is a blend of the two homozygous phenotypes(parents).
How do you xxplain how the hitchhicker's thumb trait is determined using the following words allele domnate recessive homozygous heterozygous?
basically, the hitchhiker's thumb is a physical characteristic that is inherited from your mother and/or father. when you were conceived, your mother gave you some of her genes, and your father gave you some of his. the hitchhiker's thumb is either a dominent or recessive trait. It if is dominant, you could have a heterozygous parent and still have a 100% chance of inheriting it. If the hitchhiker's thumb is recessive, you must have both of you parents homozygous for the gene to have a 100% chance of inheriting it. The alleles are either HH (homozygous dominant), Hh (heterozygous), or hh (homozygous recessive). H H << if the thumb is dominant trait, you have a 100% chance of getting it H HH HH << if the thumb is recessive trait, you have a 0% chance of getting it h Hh Hh
What is Probability of a gamete getting one of a parents two alleles of a gene?
50% as there are two alleles per gene and four gametes are made from every undeveloped sex cell.
What is the probability that certain genotypes and phenotypes will occur?
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
What information does a Punnett square provide?
Possible alleles in the gametes of the parents
What is the principle of independence party?
the law of independent assortment was formulated by Mendel. Alleles separate independently during the process of gamete production. The offspring show traits independent of the parents.
How does the alleles move?
Alleles are passed from parents to offspring through the process of inheritance during reproduction. Alleles are located on chromosomes, which are found in the cell nucleus. When gametes (sperm and egg cells) are formed, alleles segregate and are randomly distributed to the offspring, resulting in genetic variation.
What are the possible genotypes of the gametes in a genetic cross involving the keyword "genotypes"?
The possible genotypes of the gametes in a genetic cross involving the keyword "genotypes" are determined by the specific alleles present in the parents. These genotypes can be represented by different combinations of alleles, such as homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa).
What possible gametes can be produced from the f2 generation?
In the F2 generation, the possible gametes produced would be the result of the random assortment of alleles from the parents. Each parent can produce two types of gametes based on their genotype. For example, if the parents are AaBb and AaBb, the possible gametes would be AB, Ab, aB, and ab.
How are alleles passed from parents to offspring during the process of genetic inheritance?
Alleles are passed from parents to offspring through the process of genetic inheritance. Offspring inherit one allele from each parent, with the combination of alleles determining the traits they will have. This process occurs during the formation of gametes (sperm and egg cells) through meiosis, where genetic material is shuffled and passed on to the next generation.
Why is a coin toss a good way to represent allele combinations that occur in mature?
A coin flip can be used to the selection of alleles that leads to the genetic/physical makeup of offspring. Like a coin toss involves a 50/50 probability between heads & tails, the probability of offspring for inheriting either one of each parents alleles for each gene is also 50/50. Each parent has two alleles for each gene and passes one on to its offspring at random. The coin flip represents heredity. A baby's physical traits are produced based on probability determined by the traits of the parents. :-)
Who gives alleles?
Organisms inherit their alleles from their parents. In sexual reproduction, the alleles are usually inherited from two parents. In asexual reproduction, the alleles are inherited from a single cell and are genetically identical to the parent.
A tool used to visualize all the possible combination of alleles from parents?
A Punnett square is used to visually predict the potential genetic outcomes of offspring based on the alleles inherited from the parents. This tool helps understand the probability of different genetic inheritance patterns occurring in the offspring.
What is the probability of getting curly hair?
The probability of getting curly hair depends on whether your parents do or not. Hair genes are decided by the mother. So, if the mother has curly hair, more than likely the offspring will as well. If the father has curly hair and the mother does not, the probability is considerably lowered.
