scientific study of heredity

the transmission of traits from one generation to the next

a segment of DNA along the length of a chromosome that codes an organism for a particular trait

alternate versions of the same gene

a monk who develpoed ideas on heredity decades before chromosomes were observed under the microscope

a heritable feature that varies among individuals in a population

a variation within a character

organisms that produce offspring with inherited traits identical to those of the parents

combining the gametes from two different individuals

the parents from which offspring are produced in the study of heredity

the offspring of two parents that are different for one or more inherited traits

the mating of two individuals with different traits for one character

offspring of the P generation

the physical expression of a trait in a organism inherited in a gene

the genetic composition of an organism determined by the alleles it has inherited

each sperm or egg formed by a homologous chromosome separation during meiosis will contain only one of each parent's alleles, representing one trait for each inherited character

an inheritance in which the heterozygote's phenotype is an intermediate between the phenotypes of two types of heterozygotes

a mating between individuals that differ for two characters

the alleles of genes that represent different characters assort independently of each other when gametes are formed in meiosis

an organism that is heterozygous for each of the two genes being considered
