An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
If the person's genotype is Aa, then the phenotype will show the dominant form.
However, there are cases where the dominant and recessive traits are either expressed codominantly, where both alleles are expressed, or expressed through incomplete dominance, where the two alleles are partially expressed, creating a medium phenotype.
This shows a dominant phenotype but recessive genotype as in next generation there are 50 % chances.
No. An AA and SS combination can only produce an AS genotype.
I think it's genotype...
An individual with a heterozygous genotype cannot be true-bred.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
The genotype is the genetic makeup of a cell, an organism, or an individual (i.e. the specific allele makeup of the individual) usually with reference to a specific character under consideration.
50% AA and 50% Aa
Only one; A. At least concerning this one trait.
No. An AA and SS combination can only produce an AS genotype.
no they can only have children with as as as as
homozygous? homozygous? homozygous dominant
RrYy
For the two given parents: 1 offspring will have the homozygous genotype: YY 1 offspring will have the homozygous genotype: yy 2 offspring will have the heterozygous genotype: Yy
Heterozygote
offspring will be produced in following AA :Aa:aa and is in the ratio of 1:2:1 so the probabiltiy is 50%
I think it's genotype...
Dd is the heterozygous genotype for dimples.
Yes, in most societies. Genotyping is generally not done before marriage, so genotypes of the couple are unknown.
