Select the pedigree-based inferences that represent evidence that these abnormalities are a consequence of pleiotropy. The two abnormalities always occur together in an affected individual in this pedigree. A single gene is responsible for the two abnormalities. Diverse, seemingly unrelated abnormalities can be attributed to a single gene. Two genes with redundant functions result in coexpression of the abnormalities. What is the mode of inheritance for the abnormalities charted in the pedigree? Oautosomal recessive autosomal dominant X-linked dominant X-linked recessive

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.
