How many gametes will be formed in the pea plant having genotype RrTT?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2)- Two
Total possible gametes formed by a genotype is = 2n, where n is a number of genes for which it is heterozygous .
In a pea plant having genotype RrTT, number of heterozygous = 1
Total possible gametes formed by a genotype is = 2n = 21=2
In a pea plant having genotype RrTT two types of gametes will be formed i.e. RT and rT.
