Document Summary

02/12/18 lecture 7: nature vs. nurture ii: nature: genetic foundations ii, allele, some of the genes form pairs called alles. We inherit two copies of each of these genes. Genes governing traits that may take alternate forms, such as hair or eye color. If the alleles from both parents are alike: homozygous: child display the inherited trait. If the alleles from both parents are different: heterozygous: the relationship between the two alleles decide the display of the trait, dominant and recessive inheritance. In these cases, only one allele affects the child"s characteristics. Bb, bb, bb: phenotype, an observable trait, the trait that is actually seen, e. g. eye color, dominant and recessive inheritance, e. g. All people have two alleles for the gene that control whether an individual has pku. Only people with two alleles both carrying pku will have pku: dominant-recessive inheritance. Tulip color red, white, and pink: incomplete inheritance.
