On the planet hulk, in the marvel galaxy, all humanoid forms are green with extraordinary musculature. for hulks, hair texture is determined by a five quantitative trait loci. the recombination fraction between any two consecutive pairs of loci is 0.0001. the increaser allele at each locus increases the amount of extremely thick, brittle hair, whereas each locus's null allele (t) codes for extremely fine, straight hair (the "baseline" phenotype).
hair texture is measured by the "hulk - hair - o - meter" (hhom), which measures on the scales of 0.0 (extremely fine, straight hair) to 10 (extremely thick, brittle hair). those researcher brave enough to attempt to use the hhom can get very accurate measurements.
when a hulk with thick, brittle hair (hhom value of 8) and who is homozygous at all five loci mates with a she - hulk whose phenotype is extremely fine, straight hair (hhom value of two) and who is heterozygous at exactly two loci, the expected proportion of offspring with moderately thick hair (hhom value of six) is:
a. 0..
b. 0.25.
c. 0.50.
d. 0.75.
e. 0.00.
