In humans, the trait for tongue rolling is dominant over the trait for the inability of a human to roll his/her tongue. If a het
MrMuchimi

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.

Which type of change would be more likely to have se­vere consequences—substitution or deletion? Why?
