The genotypic ratio of progenie in a dihybrid test cross is
A.
9 : 3 : 3 : 1
B.
9 : 7
C.
1 : 2 : 1
D.
1 : 1 : 1 : 1
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The genotypic ratio of progeny in a dihybrid test cross is 1 : 1 : 1 : 1.A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits.
A dihybrid test cross is obtained by crossing any one parent with a heterozygous condition from the F1 generation with a parent which is double homozygous and recessive. The ratio obtained is 1 : 1 : 1 : 1.
