Achondroplasia, which is characterized by difficulty converting cartilage to bone and thus results in shortened limbs. This trait is autosomal dominant. (A = achondroplasia allele; a = average height allele.) A husband and wife both have achondroplasia. The couple have a total 12 living children: 6 boys and 6 girls.  The husband is colorblind, which is an X-linked recessive trait, and the wife believes there is a chance she is a carrier of colorblindness, since that trait runs in her family. One of the couple’s daughters and three of their sons are colorblind.  (Xc = colorblindness allele; XC = normal color vision allele.) A. What are the complete genotypes of the husband and of the wife with respect to both colorblindness AND achondroplasia. Please EXPLAIN your answer. Be sure to indicate which genotype is that of the husband and which is that of the wife.

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.
