Diagram the four types of first cousin matings possible when the sexes of the parents of the first cousins are specified. Calculate the inbreeding coefficient for an offspring of each of these matings for both an autosomal and a sex-linked locus.
Some plants reproduce by a mixture of outcrossing, selfing, and asexual reproduction.
Develop a maximum-likelihood estimator for the rate of asexual reproduction in a population segregating for two alleles at one locus. Assume that all sexual reproduction occurs through random mating. In developing your estimator use progeny arrays of the form we studied in the estimation of selfing rates. Try to figure out how you might use the E-M algorithm to arrive at a maximum likelihood estimate of the rate of asexual reproduction. A fish population biologist collects an equal number of sticklebacks from each of two adjacent habitats, a meadow stream and a nearby pool.
