Pleiotropy
In Mendel's experiments, what is the term for the situation where a cross between two heterozygous yellow mice produces yellow and brown mice in a ratio of 2:1 instead of the expected 3:1?
Lethality
What type of inheritance is characterized by a cross between two heterozygous yellow mice producing yellow and brown mice in a ratio of 2:1?
Pleiotropy
Explore the concept of pleiotropy in genetics and its contrast with the predictions from Mendel's experiments. Understand how a mutation in a single gene, as seen in Marfan syndrome, can affect multiple aspects of growth and development.
