Having wet earwax (W) is a dominant trait in humans, and having dry earwax (w) is recessive. A father has the genotype WW, and the mother has the genotype Ww. a) What is the father's phenotype? (2 points) b) What is the mother's phenotype? (2 points)

Respuesta :

The father's phenotype(physical trait) is wet earwax and the mother's phenotype is wet earwax as well.

Answer:

a) Wet ear waxed father

b) Wet ear waxed mother

Explanation:

Having wet earwax is a dominant trait in humans , represented by "W"

Having dry earwax is a recessive trait in humans , represented by "w"

When a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed.

Now  a cross is being carried between two parents having following genotype

Father - "WW"

Mother - "Ww"

a) The fathers phenotype would be "wet earwax" as both the alleles "W" are dominant allele and thus father is a "dominant wet ear waxed homozygous father"

b) The phenotype of mother is "Wet earwax" as when a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed. Thus, mother is a "wet ear waxed heterogyzous mother"
