Document Summary

Parent genotype child genotype: parent"s genetic influence on child"s genotype, human heredity, 46 chromosomes aka 23 pairs, 2 chromosomes per pair (cid:224) pairs have corresponding locations that code for the same gene (cid:224) may be 1 or. 2 allele types: pairs in 22 chromosomes are similar in size and shape (cid:224) 23 rd pair may be different, sex determination, female = xx (similar looking chromosomes, male = xy (different looking chromosomes, all eggs carry x (cid:224) sperm can carry x or y. Sperm determines sex of offspring: presence of y gene (not presence of only one x) makes the offspring male (cid:224) sry, diversity and individuality, genetic diversity from mutation and random assortment of chromosomes in egg/sperm, mutation is mutation, random assortment: one egg can get first chromosome from pair #1 and first chromosome from pair #2 and second chromosome from pair #3 (cid:224) don"t know which chromosome of the chromosome pair is going to the egg.
