gamete: haploid sex cell
gene: controls inherited trait expressions
polyploidy: 1 or more sets of all chromosomes
homologous chromosomes:1 of 2 paired chromosomes
dominant: Mendel's name for a trait in the f1 generation
phenotype:observable characteristic expressed as a result of an allele pair
diploid:2 copies of each chromosomes
genetic recombination: new combo of genes produced by crossing over and independent assortment
genetics: science of heredity
law of segregation: 2 alleles for each trait separate during meiosis
genotype: an organisms allele pairs
allele: alternate form that a single gene might have a particular trait
meiosis: reduction division process
hybrid: organism heterozygous for a specific trait
law of independent assortment: random distribution of alleles occurs during the formation of gametes
crossing over: exchange of chromosomal segments during phase 1 of meiosis
fertilization: haploid gametes combine
haploid: cell with half the number of chromosomes
recessive: specific trait masked or hidden in f1 traits
homozygous: 2 of the same alleles for a specific trait
heterozygous: 2 different alleles for a specific trait
