Plz answer my two questions. having free earlobes (f) is a dominant trait in humans, and having attached earlobes (f) is recessive. a father has the genotype ff, and the mother has the genotype ff. q1 a) what is the father's phenotype? q2 b) what is the mother's phenotype?

F = dominant, free earlobes
f = recessive, attached earlobes

father is "ff" then he has only two recessive attached earlobe alleles meaning he can only have attached earlobes. This is his phenotype, the visible trait produced by the genotype.

The mother is said to be "Ff". She has one dominant free earlobe allele (F) and one recessive attached allele (f). The dominant allele gets expressed as the visible trait (phenotype). = free earlobes

Ithink the answer is nuclear membrane
