Given: There is a two locus two allele system for a particular species of African antelope. One locus controls horn length and the two alleles are H and h. (HH) gives long horns, (Hh) gives short horns, and (hh) gives no horns. Only males can have horns. The second locus controls color pattern and has two alleles D and d. (DD) gives a dark color pattern to the face, (Dd) gives a dark color pattern to the face, and (dd) gives a light color pattern to the face. Assuming these genes are linked with a recombination frequency of 0.25 (r = 0.25 = 1/4) what will the frequency of the short horned light faced offspring be in a cross between parents of the genotypes HD / / hd (male) X Hd / / hd (female)?

(a) 0.125 or 1/8 (b) 0.2 or 1/5 (c) 0.25 or 1/4 (d) 0.4 or 2/5 (e) 0.5 or 1/2

    There is a two locus, two allele system where the ‘E’ locus codes for flower color and (EE) gives red flowers and (ee) gives white flowers and (E) is dominant. The second locus controls seed color and has two alleles, (YY) gives yellow seeds and (yy) gives green seeds and (Y) is dominant. Assuming these loci are on different chromosomes (that is, they are unlinked) what will be the genotype frequencies of the offspring be in a cross between EE...

    In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...
