Heredity and Evolution
If a heterozygous tall pea plant is self-pollinated, what will be the heterozygous: homozygous proportion of the progenies?
Correct Answer: Option(b)
Solution: Considering a heterozygous parent with T and t alleles is self-pollinated, we get two set of heterozygous progeny and two homozygous progeny.
Homozygous TT, tt =2
Heterozygous Tt = 2
Ratio Heterozygous: Homozygous = 2:2 = 1:1
So the ratio between them is 1:1
