Document Summary

Genotypes: genetic makeup of an individual. Chromosomes: rod like structures within the cells that store and transmit genetic info. Alleles: two forms of the same gene one inherited from each parents. Autosomes: 22 matching pairs of chromosomes. Gametes: sex cells - sperm and ovum. Gender chromosomes: xx & xy: xx = female, xy = male. Polygenic inheritance: characteristics influenced by many genes. Dominant-recessive inheritance: only the dominant allele affects the children"s phenotypic characteristics, many serious diseases are product of recessive alleles. X-linked inheritance: carried on the x chromosome, females are more likely to carry abnormal trait because they have two. Lateralization: two halves of the brain are not exactly alike. Homelessness in the u. s: most homeless families are women with children under 5 years old, many homeless children suffer from developmental delays and chronic emotional stress, 25-30% of school age homeless children do not attend school.
