Question

What is the probability of two tall pea plants, heterozygous for the tall allele, producing a short pea plant?

Answer 1

Hey There!

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

Total outcomes- 4 ( TT , Tt, Tt and tt )

Favourable outcomes - 1 ( tt )

P (E) - 1 / 4

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

Answer 2

So the genotype of given pea plant is Tt

When we self fertilise it will produce 3 genotypic varieties

TT Tt Tt tt

Out of 4 3 is tall . So the probability of being short 1/4
