Dna is made of a-t and c-g. Mitosis: cell duplication, where each pair of chromosomes are also duplicated. Sex linked inheritance: found on the sex chromosomes and primarily occur when boys receive a defective x chromosome, and their y chromosome cannot counteract the defective x. Xxy (kleinfelter"s syndrome): affects male physical and cognitive development: boy is born with an extra x, most common (1/500-1000 births, may involve breast development, lack of facial and body hair, potentially infertile and impaired language.
