genotype

the genes an organism has for a trait

phenotype

the trait produced by genes

alleles

different forms of a gene that cause slightly different variations of a trait

heterozygous

describes an organism with two different alleles for a trait

homozygous

describes an organism with two of the same alleles for a trait

dominant

the allele that masks the recessive

recessive

the allele that is masked by the dominant

monohybrid

cross which investigates just one trait

dihybrid

cross which investigates two traits at the same time

segregation

the separation of the 2 alleles for a trait into different gametes

independent assortment

rule which states that alleles for 2 different traits segregate into gametes independently of each other

codominance

both alleles are expressed in the heterozygote; neither allele is recessive

incomplete dominance

neither allele is fully dominant or recessive; the heterozygote is a mixture of the dominant and recessive trait

multiple alleles

type of inheritance where there are more than 2 alleles in the population for a given trait

polygenic inheritance

many sets of genes, not just one, work together to produce a trait

25%

chance that a child will have a recessive trait if both parents are carriers
