BIO207H5 Lecture Notes - Lecture 10: Mendelian Inheritance, Reciprocal Cross, Meiosis
Document Summary
Female with red eye color x male with white eye color. This 1/2 could be attributed to males receiving either the affected. W+ exhibits that has the affected eye color i. e. red. 3:1 (red eye to white eye ) but different combination. Contains only one allele for the gene. White eye female x red eye male. For each sex there is a 1:1 ratio of red eyes to whites. Females who are homozygous dominant for red eye. For males to have red or white eye. Depends on the genotype of mother as they get the x from mother. Disjunction refers to separation of the the homologs in anaphase i of meiosis. Results in gametes to have either two x chromosomes or no sex chromosomes. Results in production of four daughter cells. Two daughter cells missing one sex chromosome. Two daughter cells with an extra x.
