phenotypic ratios

what phenotypic ratio would be expected in offspring from a cross of Aa CC x aa CC if gene "a" and gene "c" were independent and A = long hair, a = short hair, C = brown coat, and c = white coat

blood types

A man with Type O blood has children with a woman who has Type AB blood. what blood types would represent the full range of possible phenotypes in children that the man and woman might have together

genotypes

A man has genotype AA, Bb, cc, DD, ee, FF. what would be the genotypes of any and all sperm he might produce considering all six genes

hemophilia

If hemophilia is an X-linked recessive trait, what percent of the daughters would be expected to be carries of the disease if a hemophiliac man had children with a woman who was a carrier of the disease?

genetics cotton tail rabbits

Consider the following hypothetical genetics information for cottontail rabbits: Ear length is controlled by one pair of co-dominant alleles (E = allele for long ears; E' = allele for short ears) located on rabbit chromosome #11. Eye color is controlled by one pair of dominant and recessive alleles (H = dom. for hazel eyes; h = rec. for dark brown eyes) located on rabbit chromosome #8. Finally, ability to produce an enzyme to digest staghorn sumac bark (sumacerase) is controlled by one pair of dominant and recessive alleles (S = dom. for production of sumacerase; s = rec. for no sumacerase production) located on rabbit chromosome #11. Which, if any, of these three traits would be consi... click for more
