PSYC 2606 Chapter Notes - Chapter 1: Methylation, Cytosine, Shampoo
Document Summary
Class 31: gene interactions complementation and epistasis: three true breeding mutants with the same disease phenotype were isolated. Aabb x aabb 50: you are studying the genetics of eye formation in fruit fly. 5 different mutant strains of fly have been isolated (a-e) a(cid:374)d ea(cid:272)h sho(cid:449)s a re(cid:272)essi(cid:448)e (cid:858)e(cid:455)e-a(cid:271)se(cid:374)t(cid:859) trait (i. e. very small or no eye). Crosses were performed as follows to test complementation, and produced progeny with + (wild-type eyes) or - (eye-absent). Course packet fall 2017: autosomal recessive mutations in two different genes cause worms to produce defective eggs. You cross together a mutant worm that lays mis-shapen eggs with a mutant that lays dead eggs. The offspring of this cross all can lay normal eggs. 9 normal eggs: 4 dead eggs: 3 mis-shapen eggs recessive epistasis. Class 32: developmental genetics i - maternal and cytoplasmic inheritance: fill in generations 2 and 3 on two pedigrees below so that they are consistent with their modes of inheritance.
