Ggenes a and b are 20 cm apart. imagine a cross involving aabb x aabb. what would the genotype of their offspring be? if that offspring is test-crossed with an aabb individual, what would be the genotypes of the progeney and in what proportions

AaBb: Aabb: aaBb: aabb

4:4:4:4

1:1:1:1

Explanation:

Alles for cross between AAbb x aaBB are -

AAbb - Ab, Ab, Ab, Ab

aaBB - aB, aB, aB, aB

a) Thus all 16 offspring that will be produced by crossing AAbb x aaBB would be  AaBb

b) Now if a cross is carried out between "AaBb" and "aabb", the following offspring will be produced-

AaBb – AB, Ab, aB, ab

aabb- ab, ab, ab, ab

AB         Ab        aB        ab

abAaBbAabbaaBbaabb

abAaBbAabbaaBbaabb

ab AaBbAabbaaBbaabb

ab AaBbAabbaaBbaabb

The genotypic ratio is  

AaBb: Aabb: aaBb: aabb

4:4:4:4

1:1:1:1
