Document Summary
Lecture 3: human heredity part ii transmission of genes from generation to. Chromosomes separate during meiosis for gamete formation. Brought in the idea of dominant and recessive relationships. When a person is dominant, the pedigree will show that trait in every generation. Only one copy is required for offspring to be affected. Recessive pops up on the pedigree sporadically. X-linked males are mostly affected since they only have one chromosome. If a person is not expressing type a or b antigens, it is not type o if it has the bombay allele. This is because the precursor to a and b antigens is a protein called h, Bombay trait inhibits this h protein and is neither blood type a, b, or o.
