PHGY 210 Lecture Notes - Lecture 4: Chi-Squared Distribution, Mendelian Inheritance, Gamete
Document Summary
Genotype of iiii-1: t/t b/c offspring is t/t and mate is t/t and taster has to have t to be unaffected and t for offspring. Offspring are all tasters, possible that t allele was not passed on ( * * * = 1/16 ) Although probability of above is small, still take into account so t/_ is a better answer than t/t. Both alleles enter pedigree at generations ii and iii b/c condition is not rare. Mendel studies 7 separate traits, the genes for these traits were located on 7 chromosomes. If all the genes were on the same chromosome, then independent assortment would not have been observed. Parents produce gamete types: r, y and r, y. F1: double heterozygote r/r y/y, dominant conditions shown: yellow and round. 315 : 108 : 101 : 32 ~ 9:3:3:1. Desired traits: d/d f/f and self-pollinate to obtain more seed. F2 expected = 1 ww: 2 ww: 1ww.
