سؤال 51

A pea plant has the genotype Bb. Which gametes can it make for this gene?

Gametes carrying both alleles at once
Only gametes carrying the dominant allele B
Gametes carrying B and gametes carrying bپاسخ درست
Only gametes carrying the recessive allele b

توضیح

The two alleles separate as gametes are formed, so each gamete receives one of them and the plant makes the two types in equal proportion. A gamete holding both symbols would double the allele count, leaving the offspring with three alleles of the gene after fertilisation.
