1. In humans, hair type shows incomplete dominance curly hair is represented by the
genotype HH, wavy hair is Hh and straight hair is hh. Cross a curly-haired individual with a
wavy-haired individual show the cross in a Punnett square and list the expected
genotypic and phenotypie ratios.
a) Genotypic ratio:
b) Phenotypic ratio:
2. Albinism (little or no pigment in eyes, hairs and skin) is recessive among humans (a) and
producing pigment is dominant (A). If you cross two heterozygous individuals for this trait
what are the genotypes and phenotypes that can result? SHOW THE PUNNETT SQUARE!
