Question | Answer |
Heredity | The passing of genetic traits from one parent to offspring |
Dominate Trait | trsit observed in the first generation when parents that have different traits are bred. |
Recessive Trait | a trait that is apparent only when two recessive alleles for the same characteristic are inherited |
Gene | one set of instructions for an inherited trait |
Allele | one of the alternative forms of a gene that governs a chasracteristic,o such as hair color. Can be dominate or recessive |
Phenotype | an organism's appearance or other detectable characteristic |
Genotype | the entire genetic makeup of an organism; also the combination of genes for one or more specific traits( ex: allele Pair: BB, Bb, bb) |
Probability | the likelihood that possible future event will occur in any given instance of the event |
Homologous Chromosome | chromosomes that have the same sequence of genes and the same structure |
Meiosis | a copying process that produces cells with half the ususal number of chromosomes |
Sex Chromosome | one of the pair of the chromosomes that determine the sex of an individual |
Pedigree | a tool for tracing a trait through generations of a family |
Genetic Engineering | Used to help produce large volumes of medicine; change how cells look or perform |
Genetics | the study of traits |
Heterozygous | describes an organism with two different alleles for a trait |
Homozygous | describes an organism with two alleles that are same for a trait(BB-homozygous recessive, bb- homozygous dominant) |
Incomplete Dominance | phenotype between two homozygous parents, does not show true dominance. (ex: AB blood) |
