Mendelian Genetics Review Questions And Answers Rated A+ New Update Assured Satisfaction

"Law of Independent Assortment" - Each trait is inherited differently "Law of Segregation" - Each trait is controlled by two copies of a gene Allele - different forms of the gene Amnio Centisis - Medical procedure that proves gender of baby and any abnormalities Autosomes - all other chromosomes that are not the sex chromasomes Blood genotypes for; A, B, AB, O - A=Ao, AA. B= BB, Bo AB=AB O= oo Chorionic Villus Sampling - test made early in pregnancy to check chromosomes to see if there are any abnormalities Co-dominance - Each allele contributes to the phenotype, ex: black chicken with speckled white dots Complete Dominance - The dominant allele is masking the recessive. Ex: Xx Crossing Over - process in genetics by which 2 chromosomes of homologous pair exchange equal segments w/ each other Dihybrid cross - follow 2 pairs of genes from parent to offspring. Ex: TtWw * TtWwDominant - Dominant alleles masks or dominates other genes, represented with a capitol letter F1 generation - First filial- second generation F2 generation - Second filial- 3rd generation Genes - Determine traits passed from generation to the next Genetics - The study of how traits are transmitted from parent to offspring Genotype - "genetic makeup", "the genes". they are the letter used to describe the genome, ex: pp, PP, Pp Heredity - Passing of traits from parent to offspring Heterozygous - The alleles are different. Ex: Pp Homozygous - the alleles are the same. Ex: RR, DD, rr, dd Human Genome project - Project where the goal was to map the whole human genome Hybrid - when alleles are heterozygous incomplete dominance - One allele is not completely dominant over the other heterozygous phenotype. ex: Red * White= pink Karyotype - The number and visual appearance of the chromosomes in the cell of an organism or speciesMultiple allele traits - Genes with two alleles. Ex: human blood Nondisjuntion - when one or more pairs of homologous chromosomes or sis chromatids fail to divide during nuclear division causing abnormalities P generation - Parental generation, First Generation
