Two families are genotyped at a marker with alleles M and m. Genotypes at a disease gene, with alleles D and d, are inferred from the larger pedigrees (not shown). The genotype of each individual is displayed below. The phase of each individual is indicated with a horizontal bar. One chromosome has the combination of alleles above the bar and the other chromosome has the combination of alleles below the bar. Use this information to complete the following tasks: A. Labeling the children as 1, 2, and 3 moving from left to right along the chart, indicate whether each child's genotype arose from a recombinant or non-recombinant gamete from their heterozygous parent. B. Write down the formula for the combined odds ratio across the two families for linkage vs. no linkage as a function of the recombination frequency (r). You do not need to simplify your expression.

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.
