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.
No, an AAA and SS combination can only produce an Aa genotype. The offspring will inherit one allele from each parent, resulting in a heterozygous genotype. For an AAA genotype to be produced, both parents must have the same alleles for the specific gene.
You cannot do a cross to determine the genotypes of individuals because there is only one gene here. Genotype consists of the entire genetic makeup of the individual, which cannot be determined by a single gene. Only the alleles S or s is used to express this particular gene. If you're looking for a monohybrid cross between Ss and Ss, while separately wanting a result between ss and ss, then the answers are as follows: Ss x Ss 25% SS 50% Ss 25% ss ss x ss = 100% ss
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.
I think it's genotype...
The genotypic ratio for two parents with the genotypes AAA and AAA is 1:0. This means that all offspring will have the genotype AAA.
50% AA and 50% Aa
No, an AAA and SS combination can only produce an Aa genotype. The offspring will inherit one allele from each parent, resulting in a heterozygous genotype. For an AAA genotype to be produced, both parents must have the same alleles for the specific gene.
The predicted ratio of offspring in a mating of AAA and AAA would be 100% AAA. Since both parents have the same genotype, all of their offspring will inherit the same genotype.
no they can only have children with as as as as
homozygous? homozygous? homozygous dominant
Only one; A. At least concerning this one trait.

The genotype Kk can be described as heterozygous for a specific gene, meaning that the individual has two different alleles for that gene. In this case, one allele is dominant (K) and one is recessive (k). The dominant allele will determine the phenotype in this case.
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
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.
I think it's genotype...
offspring will be produced in following AA :Aa:aa and is in the ratio of 1:2:1 so the probabiltiy is 50%
