Diagram the genotypes of the P1 monohybrid, which produce round seeds to wrinkled seeds in the ratio
of 3:1. Rounds seeds are dominate. Use the letters R and r to denote genotypes. Fill in the blanks to
complete the Punnet square.

Respuesta :

The genotypes of the P1 monohybrid cross that produce round seeds (R) to wrinkled seeds (r) in the ratio of 3:1 is equal to 3 R_ : 1 rr. It occurs when two heterozygous are crossed.

Genetic dominance and Punnett square

Genetic dominance refers to the phenomenon in which the dominant allele masks the expression of the recessive allele in heterozygous individuals.

In this case, both parents can produce two types of gametes, i.e., either 'R' or 'r'.

In a Punnett square:

            R            r

R          RR         Rr

r            Rr         rr
