homozygous recessive individual

Is it possible for offspring of a homozygous recessive individual to show the dominant phenotype? If yes, what would have to be true?

phenotypes

a man who has free earlobes marries a woman who has attached earlobes. What would be the expected phenotypes ( and ratios or percentages) of off spring if the man were homozygous? Assume E= dominant allele for free earlobes and e - recessive allele for attached earlobes)

genotypic and phenotypic ratios

what would be the expected genotypic and phenotypic ratios in the F1 and F2 generatiosn, if flower color in carnations is controlled by co-dominant alleles and you begin with the P generation using pure, or true-breeding, carnations that have different (red & white) flower colors?

Red - green colorblindness

A colorblind woman marries a man with normal color vision. What percentage of their sons would be expected to be coloblind, what percentage of their daughters would be ecpected to be colorblind explain answers about sons and duarghters that would be expected to be colorblind in genetic words.

Breeding

A geneticist determines that long hair length in mink is dominant over short hair (recessive). his friend breeds mink in captivity with long hair esp for the fur inducstry and has received permission from the Kansas Department of Wildlife and Parks to trap 5 wild mink to add to his breeding stock to reduce effects of inbreeding within his colony, but he wants to otherwise maintain production of all long-haired mink. 4 of the 5 wild mink have long hair, the 5th has short hair. If he has room to house only 2 more mink as breeding stock during the subsequent 5-year period, explain how his geneticist friend should advise him to procced in conducting a test cross to detemine which (if any) of ... click for more
