AA X aa= 4 Aa======the only possible cross between a true breeding homozygous dominant and a true breeding homozygous recessive.
The genetic makeup AAA BB is called its genotype. It is defined as the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
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
Since they are capital letters they stand for a dominant allele. Both the letters stand for a different trait. This is saying these two different organisms were dominant in those specific traits.
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.
Homozygous refers to having two identical alleles in a given trait.
It is called Homozygous.
AAa
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
It's impossible to say without more information. The genotype AA is called homozygous dominant for the trait that is encoded by the letter A (or a). Whatever trait A stands for on your homework, the answer is the dominant one is expressed in the phenotype.
