Sex Chromosome Meiosis
During meiosis in a human male, nondisjunction happened with the sex chromosomes for one of the daughter cells during meiosis II.
Draw out this meiosis and show all possible resulting gametes. Label the chromosomes at every step.
What possible conditions can occur, including normal male or female if applicable, if these sperm fertilize normal eggs? List all possible genotypes of offspring. Then add the names of each condition next to the genotype for the conditions that have names.
What fraction of offspring would you expect to have each genotype/condition?
