A heterozygous parent self fertilizes and the progeny are collected. Ten of these offspring form wild-type plants and nine are homozygous recessive mutants? Calculate the probabilities of this distribution by chi-square analysis (report the P value in the chart closest to your chi-square value).
Read DetailsAssume that the genes for tan body and bare wings are 8 map units apart on chromosome II in Drosophila. Assume also that a tan-bodied, bare-winged female was mated to a wild-type male and that the resulting F1 phenotypically wild-type females were mated to tan-bodied, bare-winged males. Of 1000 offspring, what would be the expected of wild-type offspring, and in what numbers would they be expected?

Read DetailsLaw enforcement personnel request your assistance for a 30-year-old man who they pulled over for erratic driving.

When you arrive and assess the patient, you find that he is very agitated and is experiencing apparent hallucinations. His skin is flushed and diaphoretic. You should:
Read DetailsThe genes for miniature wings (m) and garnet eyes (g) are linked on chromosome 1 in Drosophila. Phenotypically wild-type females that were heterozygous for both loci were mated to miniature-winged males with garnet eyes. The resulting progeny were: 38 miniature wings, red eyes 42 wild-type wings, garnet eyes 5 miniature wings, garnet eyes 5 wild-type wings and eyes The best explanation for this is:
