4. Can you curl your tongue up on the sides? tongue-curling in humans is a dominant genetic trait. Suppose a man who is tt for tongue-curling marries a woman who is also tt for this trait. What are the possible genotypes and phenotypes of their children and the percent chance for each?.

Respuesta :

The possible genotypes and phenotypes of their children and the percent chance for each is 0%.

  • The capacity to roll one's tongue outweighs the lack of capacity.
  • The two people have the homozygous recessive character if the dominant allele is R and the recessive allele is r.
  • This indicates that the organism's genotype will be "rr."

If such people cross each other:

Parents X Parents

gamma r r

Children rr

That results in :

  • The genotype of the offspring will be homozygous recessive (rr) based on the genetic cross.
  • Because they lack the dominant allele, the child will therefore be unable to roll their tongue.

The possible genotypes and phenotypes of their children and the percent chance for each is 0%.
