Genetics the scientific study of heredity
fertilization the joining of gametes
trait a specific characteristic
genes factors that determine specific traits
allele alternate form of a gene
dominance states that certain alleles express themselves of overs
segregation states that only one allele cab be passed on because of the separation of alleles during gamete
formation
probability the likely hood of a particular event
homozygous two identical alleles for a trait
heterozygous two different alleles for a trait
phenotype expressed physical characteristics
genotype the genetic makeup or nucleotide sequence
independentassortment no set rules for the alignment of homologous chromosomes during meiosis
incompletedominance a new phenotype is produced
codominance both alleles contribute to the phenotype
multiplealleles more than two alleles contribute to the phenotype
polygenictraits controlled by two or more genes within a person
genemap shows the distance between genes on a specific chromosome
Mendel the father of genetics
gamete sperm or egg cells used for reproduction
