Course content on owl: psych practice exam answers on separate file. Q: you have dark hair (dominant) if we examined your karyotype, we would find that your alleles for hair colour were: Dominant produces effects in either homozygous (bb) or heterozygous (bb) mode. Recessive produces effect in only homozygous (bb) This doesn"t indicate extent to which genes are responsible. Taps relative contribution of genes to overall variation in population. This only applies to the group you"re studying and measuring. Calculation of area: when width stays constant and length changes: Differences in area is due to more of changes in length, rather than width: when length stays constant and width changes: Differences in area is due to more changes in width, rather than width. Hair colour in inuit: heritability is 0, h2=0, but genes are responsible of expression of hair. H2 increases as genetic diversity increases (more genotypes higher. H2 decreases as environmental diversity increases colour heritability)
