Lecture 5 1) Heritability usually ranges from .1 to .6 (theoretically from 0 to 1). 2) To test heritability of traits – you could do a garden variety test, or out in the field, you could swap the eggs and see if the chicks resemble their foster parents or biological parents more. 3) Genome of the mosquito – 3 pairs of chromosomes (haploid complement (N) = 3) a) Locus – specific place on the chromosome where an allele is located b) Allele – DNA sequence at a specific locus. 4) Sources of genetic variation: a) Mutation – the ultimate source of all genetic variation b) Genetic Recombination - Crossing over, independent assortment, random union of gametes. Source of variation in individuals . 5) Alterations of chromosome structure a) Duplication – if B’ starts to get mutations and alter the protein structure, it might not make the zygote unviable because the original B is there. Important because this can lead to new function. 6)
