When an individual has two different alleles, whether dominant or recessive
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote
cross breed, is the result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
A trait that is controlled by a group of nonallelic genes.
predicting the outcome of a genetic cross or of a random experiment
stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together
is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele
a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n
the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring
When an individual has two of the same allele, whether dominant or recessive
containing two complete sets of chromosomes, one from each parent
Down

the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote

any one of a series of three or more alternative or allelic forms of a gene, only two of which can exist in any normal, diploid individual
A condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other
structure is an organ, system, or body part that shares a common ancestry in multiple organisms
the study of heredity and the variation of inherited characteristics
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell
