A pea plant that is heterozygous for the flower color gene makes gametes. What is the probability that a specific gamete contains the recessive allele for flower color?

1/2

Explanation:

Assuming the gene is represented by the allele G (dominant), the alternate form (recessive) of the allele will be g.

A heterozygous pea plant will have the genotype Gg. During gamete formation, Gg will split into G and g gametes.

The probaility that a gamete will contain the recessive allele for flower color is 1/2.
