Document Summary

Chromosomes: store and transmit genetic information, 23 pairs of chromosomes. Dna: substance of which genes and chromosomes are made. Genes: segments of dna located along the chromosomes. 22 pairs of chromosomes that are not sex chromosomes. Xo=turners, look like a girl but don"t develop as a female. Xxy=klinefelter"s, look like males, but act like a female. One zygote that divides into two individuals. Two females are more common then two boys. Forms of the same gene on a pair of chromosomes. Appear at the same place on each chromosomes in the pair. One allele is inherited from each parent. To determine the sequence of the chemicals that make up the human. Aims to improve human health and fighting disease through genomic research. Mendel argued that certain traits are transmitted from parents to child. Each trait is governed by two elements with one from each parent. Genotype: refers to the underlying genes that govern the trait.
