Document Summary
Biol 202 lecture 2: multiple gene inheritance i. Mitotic separation and have alleles in them. You can get variegated phenotypes by unequal division where you get a and a alleles. Starts as a diploid, divide twice (meiosis 1 & 2), and ends up with 4 haploids. Has post meiotic mitotic division (helps evolution) The way it segregates its chromosomes is incredibly interesting. Evidence for organelle based inheritance (ie: cytoplasmic inheritance) For nueropsora: mitochondria came from the mother, nuclear dna comes from the father. Female gamete is massive compared to male gamete! If they"re in the germ line of the mother, you"ll most likely inherit things. !1: a lot of muscle de ciencies happen in the mitochondria, which means that the mothers will most likely pass them down to their children. Practical applications: assembling useful genes in modern crop varieties by breeding (disease resistance, drought tolerance, ancient crop varieties)
