Transcript
Augustinian monk and botanist whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics (1822-1884) Mendel a type of gene that is hidden by a dominant gene Recessive used to show the possible gene combinations in a cross between two organisms Punnett Square a gene responsible for determining traits in an organism Allele chromosomes that do not determine the sex of a person Autosome HH Homozygous Dominant pattern where the phenotypes of both homozygous parents are present in heterozygous offspring; both alleles are equally expressed Codominant Alleles the stronger trait in a gene pair Dominant union of a sperm and egg Fertilization the branch of biology that studies heredity and variation in organisms Genetics an organism's genetic makeup, or allele combinations Genotype an organism that has two different alleles for a single trait, for example (Hh) Heterozygous two of the same alleles for a trait, for example (HH) Homozygous an organism that is heterozygous for a particular trait Hybrid a genetic pattern in which neither of the two forms of a trait completely masks the other Incomplete Dominance any chromosome other than a sex chromosome Autosome a picture of all the chromosomes in a cell arranged in pairs Karyotype having more than two alleles that control a trait Multiple Alleles a chart or "family tree" that tracks which members of a family have a particular trait Pedigree what an organism looks like as a consequence of its genotype Phenotype transfer of pollen from the anther to the stigma of a plant Pollination hh Homozygous Recessive occurs when groups of gene pairs act together to produce a specific trait Polygenic Inheritance a trait that will be masked by more dominant trait Recessive X and Y chromosomes that determine the sex of an individual Sex Chromosome characteristics that are inherited Trait heterozygous offspring show a phenotype that is in between the phenotypes of the two homozygous parents Incomplete Dominance Hh Heterozygous Punnett Square b B B b b b B Bb Bb B Bb Bb
