Genes : DNA segments
Homologous Chromosomes : chromosomes that make a pair (one from each parent)
Genetics : science of hereditary
Homozygous :an organism with 2 of the same alleles for a trait (YY, yy)
Heterozygous : an organism with 2 different alleles for a trait (Yy)
Genotype : genetic makeup of an organism (YY, Yy, yy)
Phenotype : physical makeup of an organism (Yellow, green)
Laws of Segregation : ”two alleles for each trait separate during meiosis”
Hybrids : heterozygous organism
Karyotype : homologous chromosomes arranged in decreasing size
Telomeres : protective function for chromosomes structure (caps)
Nondisjunction : when sister chromatids fail to separate completely
Nucleosome : repeating subunit of chromatin fibers , consisting of DNA coiled around histones
Selective Breeding : desired traits for certain organisms are passed down
Inbreeding : breeding to have desired traits and get rid of undesired traits
Test Cross : breeding and organism that has the unknown genotype with one that is
