Allele - alternative form of a gene (one member of a pair) located at a specific position on a specific chromosome (a letter) Codominance - occurs when BOTH alleles of a gene are expressed in an individual (ex. Black + White = Black & White Speckled) Dihybrid cross - a two-trait cross (ex. color & shape) Dominant Allele - an allele that produces the same phenotype whether its paired allele is identical or different (capital letter) F1 Generation - first filial generation is the generation...

allele - variant form of a gene codominance - hetero shows both pheno from the two alleles complete dominance - hetero shows same pheno as homo Epigenetics - change in phenotype without changing genotype Father has blood type A. Mother has blood type B. Child has blood type O. What are the genotypes of the parents? - IAi and IBi Father has blood type B. Mother blood type O. Child has blood type O. What is the chance of them having another two children who both have the blood type O. - 1/4...

"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 th...

allele - one form or version of a gene asexual reproduction - a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only codominance - type of dominance that occurs when the contributions of both alleles are visible in the phenotype complete or simple dominance - type of dominance that occurs when an inherited trait is coded for by a single gene and that gene has two versions, or alleles: the dominant version and the recessive version...

46 - the number of chromosomes that humans have allele - one form or version of a gene complete or simple dominance - type of dominance that occurs when an inherited trait is coded for by a single gene and that gene has two versions, or alleles: the dominant version and the recessive version, where the dominant version masks the recessive version dihybrid cross - cross that follows TWO traits dominant - the allele in a genotype that masks the contribution of a second allele at the same lo...

A cross involving true-breeding, red snapdragons and true-breeding, white snapdragons produce all pink offspring because both genes are present, neither being ________ over the other resulting in the ________ of the trait. - • dominant • blending Choose the answer that shows the cross between roan and white cattle. - Rr x rr Complete the following Punnett square showing the genotypes produced from crossing agouti with a chinchilla with the following alleles: A=agouti, C=chinchilla, a=...

23 chromosomes - each parent contributes this many chromosomes to their offspring in humans. 46 chromosomes - Full set of chromosomes in a normal human cell. Adele - Set Fire To The Rain Allele - the different forms of a gene. Centromere - area where the chromatids of a chromosome are attached Codominance - situation in which both alleles of a gene contribute to the phenotype of the organism Crossing over - process in which homologous chromosomes exchange portions of their chromatids dur...
