X and Y: the Genetics of Sex-linked Genes (with practice questions!)

Practice questions start at 11:44. The genetics of sex-linked genes is a little different because females inherit two X chromosomes while males inherit an X and a Y chromosome. This video breaks down how biological sex is determined and the possible results of genetic disorders carried on the X chromosome. 00:19 How X and Y are different from the autosomes 01:45 How X and Y are inherited 02:35 How biological sex is determined 06:14 "Sex-linked genes" and why we care 07:11 How X-linked genes are inherited and offspring possibilities 11:19 Genetic disorders or diseases carried on the X chromosome 11:44 #1. Chance of male passing along the color-blindness trait? 13:17 #2. Chance of female passing along the trait? 14:20 #3. Proportion of children with color blindness? 16:04 #4. Proportion of female children with color blindness? 17:12 #5. Proportion of female children who are carriers? 17:40 #6.
