Hair texture in humans is an example of incomplete dominance. If a man with curly hair has children with a woman with straight hair, all the children has an intermediate texture that is wavy hair. What is the likely proportion of phenotypes in their children?

100% Wavy hair

Explanation:

The gene involved here codes for hair texture in humans. The alleles of the gene (straight, S and curly, s) exhibits incomplete dominance. Incomplete dominance is a genetic scenario whereby one allele does not completely mask the expression of the other allele, instead an intermediate phenotype that is heterozygous is formed.

In this case, a man with curly hair (ss) marries a woman with straight hair (SS). The children from this cross will all possess a heterozygous genotype (Ss) and be phenotypically wavy-haired, since Incomplete dominance is exhibited by the gene. Therefore, 100% of the offsprings/children will have wavy hair phenotype.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
