You place a sma-2 homozygous hermaphrodite and a wild-type (+) homozygous male on a Petri dish. Provide the phenotypic and genotypic ratios, showing all work, for an F(1) cross between these two C.elegans. Then provide your interpretation as to whether the mutation is dominant or recessive and a brief explanation […]

A population of Hawaiian Drosophila has two alleles (M and m) of a particular gene. In a sample of 100 flies from this population, 3 were MM homozygotes, 60 were Mm heterozygotes, and 10 were mm homozygotes.  Perform a chi-square test, to test the hypothesis that the observed numbers of […]

A. At one time the continent of Australia was connected to Asia. About 50 million years ago Australia became separated.
