Below is a pedigree of a family with a history of X-linked recessive color blindness. We will use XB to represent the wild-type allele and xb to represent the mutant allele of the gene that leads to color blindness. The color vision status of the individuals with a question mark (?) is unknown. Part 1 Drag the correct genotype for each individual to the boxes under the pedigree symbols for the first two generations. 11. III. xBxB xbxbxby xbxBxBxB or xbxB O 1/4 Part 2 What is the probability that the female child in Generation III will be color-blind? 01/2 O 3/4 00 O1/4 Part 3 What is the probability that the male child in Generation III will be color blind? 1/2 ? xBy 3/4 00

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
