a fruit fly of genotype Aa Bb is crossed to anotehr fruit fly of genotype aa bb. the progeny of this cross were

Please find the progeny of this cross below:

AaBb (1/4)

Aabb (1/4)

aaBb (1/4)

aabb (1/4)

Explanation:

According to this question, a fruit fly of genotype AaBb is crossed to another fruit fly of genotype aabb. This cross is a typical dihybrid cross involving two genes A and B. The following gametes will be produced by parents of this cross:

AaBb- AB, Ab, aB, ab

aabb- ab, ab, ab, ab

Using these gametes in a punnet square (see attached image), 16 offsprings or progeny in following proportion will be produced:

- AaBb (1/4)

- Aabb (1/4)

- aaBb (1/4)

- aabb (1/4)

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
