Document Summary
Lecture 11 lecture: way in which inheritance of polygenic traits show that inheritance is not blended Intermediate parents can have extreme children. red and blue paints back from mixing purple paints. If you mix red paint and blue paint, you get purple paint. You shouldn"t get: this shows inheritance isn"t blended. 9:3:3:1 ratio of two different traits (like pea shape and colour: sex chromosome combinations can produce recessive sex linked traits. In drosophila, the allele for white eyes is recessive to the allele for red eyes. If a homozygous red eyed female breeds with a white eyed male, all offspring will be red eyed. In meiosis, the cells will arrange their chromosomes randomly. 50/50 to each pole: half the meiocytes will give two gametes, half will give two different gametes (if dihybrid), the organism as a whole produces four different gametes. Independent assortment creates variation in the segregation of chromosome.
