It is about the chromosomes, DNA and inheritance

Chromosomes are structures that contain the genetic material, which is DNA. EXPLAIN what will happen if the chromosomes were not condensed and DESCRIBE the important events during meiosis that result in a half reduction in the amount genetic material per cell. Polydactyly is a rare dominant trait found frequently in people of African American descent in which the hand has one more or more extra fingers. A male with polydactyly, who has a mother with non-polydactyly, moves to an island that is inhibited by people who are not of African American descendant. Assuming that no other African American immigrate to the island, CALCULATE the probability that a great grandchild of this male will have polydactyly and briefly EXPLAIN your answer.
