Genetics

The study of heredity and the variation of inherited characteristics.

Heterozygous

Having two different alleles for a particular gene.

Homozygous

Having two identical alleles for a particular gene.

Phenotype

The physical expression or characteristics of an organism's genotype.

Genotype

The genetic constitution of an organism, represented by its alleles.

Segregation

The separation of alleles during gamete formation, leading to offspring with different traits.

Recessive

An allele that is masked by a dominant allele and only expresses in a homozygous condition.

Dominant

An allele that masks the effect of a recessive allele in a heterozygous condition.

Alleles

Different versions of a gene that can exist at a specific locus on a chromosome.

Gene

The basic unit of heredity that carries genetic information.

Hybrid

An organism that has two different alleles for a trait.

True-breeding

Organisms that produce offspring identical to themselves when allowed to self-pollinate.

Trait

A specific characteristic of an organism, often determined by its genotype.
