Suppose you return to the population after 10 generations and observe 80 black, 240 brown and 180 tan individuals. Explain how you would use the H-W model to determine if there has been statistically significant evolutionary change (change in genetic composition) in the population. Include the following terms in your answer: null hypothesis, observed and expected genotype frequencies, chi-square. Recall that you would need to do the chi-square calculation using observed and expected numbers of individuals of each genotype, not using observed and expected frequencies.

Suppose that you have gloves of 4 colours in the drawer: black, brown, grey and white, 6 pairs of each colour. Every glove is either left or right and does not fit on the other hand. If you are taking gloves out in the dark, without looking, what is the minimum number you need to take out to guarantee that you have a pair (that is, a left and a right of the same colour)? What is the minimum number...

1. Suppose that you are studying coat colour (black vs. grey) in a wild population of rabbits a. Crosses between various pairs of black rabbits produce all black offspring. Is it possible to conclude that black is the dominant trait? b. Crosses between various pairs of black and grey rabbits produce F1s that are both black and grey. Is it possible to conclude how the traits are inherited based on these results? c. Crosses between the F1s in b. sometimes...

You are studying the genetics of the fruit fly. Body color (brown or black) is controlled by the b locus and wing size (long or short) is controlled by the vg locus. In cross 1, you mate two true-breeding strains and obtain the following progeny: cross 1: brown, short-winged male X black, long-winged female F1: all brown, long-winged flies a) Which phenotypes are dominant and which phenotypes are recessive? i) The recessive trait for body color is _____________________. ii) The...
