5) You have a cross of a ¾ M ¼ N female with a ¾ O ¼ N male. The female was the result of a M x MN mating, and the male was the result of an O x ON mating. Calculate the percent direct and maternal heterosis.

Maternal effect genes are a special class of genes that have their effect in the reproductive organs of the mutant. They are interesting because the mutant organism may appear phenotypically normal, and it is the progeny that express detectable differences, and they do so whether the progeny have inherited the mutant gene or not. The first maternal effect gene identified was the gene controlling shell coiling in the water snail Lymnaea peregra. Alleles of this maternal effect gene are non-lethal...

D. 25% orme condition. The male is XX and the female is XY. But X-linked genes have the same effects in mugwumps as in humans. A recessive X-linked allele "n" produces red-green color blindness. The dominant allele "N" produces normal color vision. If a female mugwump with normal color vision mates with a male mugwump, phenotypically normal for color vision but whose mother was color blind, what is the probability that a son from that mating will be color blind?...

You make cross between a male fruit fly with wrinkled wings and a female fly with vestigial wings. All of the F1 flies are have wrinkled wings. A cross between an F1 female fly and an F1 male fly yields the following offspring: 45 wrinkled-wing males 51 wrinkled-wing females 18 vestigial-wing males 14 vestigial-wing females What do you hypothesize as the mode of inheritance for this trait?

In rainbow trout, you are studying scale color and patterning. You have identified two genes: R = rainbow scale color, where loss of function confers a "gray-scale" color phenotype. S = stripe pattern, where loss of function confers a spotty pattern phenotype. You cross a rainbow horizontal striped fish to a gray spotty fish with the following strange result: (Female) RRSS x (male) rrss -> RrSs with phenotype gray and striped. Which parent was the recessive gray allele inherited from,...
