In a population, genes A and B, each with two alleles, are linked. There are 4 individuals with haplotype "AB", 2 with 'ab' and 2 with 'ab' and 2 with 'aB'. Calculate linkage disequilibrium (D), where D = P(AB) - P(A)P(B) (where P(AB) is the frequency of that haplotype, and p(A) and P(B) are the frequencies of those individual alleles

Dominant alleles at two different loci affect the tail of mice. These genes are linked and both are lethal in the embryo when homozygous. One of the tail genes is called brachyury (T), and these mice have short tails. A third gene, histocompatibility-2 (H-2), is linked to the tail genes and is concerned with tissue transplantation. Mice that are H-2/+ will accept tissue grafts, unlike +/+. A cross was carried out between male T H-2/ + + and female +...

Which one of the following is the best explanation for Haldane’s rule? A. Deleterious recessive alleles on the sex chromosomes that cause incompatibility between two species will not be masked in the heterogametic sex, but will be masked in the homogametic sex. B. New, deleterious combinations of alleles at two or more autosomal loci are present in hybrids, and those deleterious combinations of alleles do not occur in the species that gave rise to those hybrids. C. Random fluctuation of...

Loci A and B are linked. Two heterozygotes are crossed. Individual one makes gametes in which both alleles in the gamete are either dominant or recessive (i.e. AB). The other organisms makes gametes in which the alleles are mixed (i.e. Ab). What is the phenotypic ratio of the offspring if the progeny if having dominant forms of both alleles produces a distinct phenotype versus those progeny having only one dominant allele?
