50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.
Explanation:
Information given:
the ability to roll tongue is dominant, the genotype would be RR, Rr
the inability to roll tongue is recessive trait the genotype = rr
Given that heterozygous male is crossed with homozygous recessive female, the genotype is
Rr X rr
Punnet square shows that:
R r
r Rr rr
r Rr rr The genotype ratio is 1:1
phenotype ratio is 1:1
There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.
