One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

An allele that produces the same phenotype whether its paired allele is identical or different; it "masks" the expression of a recessive allele.

The scientific study of genes, genetic variation, and heredity in organisms

The genetic constitution of an individual organism (e. g., (AA),(Aa), or (aa)

An individual having two different alleles of a particular gene or genes (e.g., Aa).

An individual having two identical alleles of a particular gene or genes (e.g., AA or aa).

An offspring resulting from the cross of two genetically different parents or varieties.

law of independent assortment

Mendel's law stating that genes for different traits are inherited independently of each other during gamete formation.

Mendel's law stating that the two alleles for a trait separate during meiosis, so each gamete receives only one allele.

The specific physical location or position of a gene or DNA sequence on a chromosome.

The observable physical characteristics or traits of an organism, determined by its genotype and environment.

Fine powder containing the male gametes (sperm cells) of seed-producing plants.

The transfer of pollen from the male part of a plant (anther) to the female part (stigma).

An allele that is only expressed in the phenotype when two copies are present (homozygous).

A condition in which both alleles for a gene are fully and equally expressed in the phenotype of the heterozygote (e.g., a cow with both red and white hairs).

A pattern of inheritance where the phenotype of a heterozygote is an intermediate blend between the two homozygous phenotypes (e.g., red and white flowers producing pink offspring).

polygenic characteristic

A trait that is controlled by the interaction of multiple genes, often resulting in a wide range of phenotypes (e.g., human skin color or height).

The mathematical likelihood that a specific event or outcome will occur, used in genetics to predict the chances of offspring inheriting certain traits.

A grid or diagram used to predict the possible genotypes and phenotypes of offspring from a particular genetic cross.

Question	Answer
allele	One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
dominant allele	An allele that produces the same phenotype whether its paired allele is identical or different; it "masks" the expression of a recessive allele.
genetics	The scientific study of genes, genetic variation, and heredity in organisms
genotype	The genetic constitution of an individual organism (e. g., (AA),(Aa), or (aa)
heterozygote	An individual having two different alleles of a particular gene or genes (e.g., Aa).
homozygote	An individual having two identical alleles of a particular gene or genes (e.g., AA or aa).
hybrid	An offspring resulting from the cross of two genetically different parents or varieties.
law of independent assortment	Mendel's law stating that genes for different traits are inherited independently of each other during gamete formation.
law of segregation	Mendel's law stating that the two alleles for a trait separate during meiosis, so each gamete receives only one allele.
locus	The specific physical location or position of a gene or DNA sequence on a chromosome.
phenotype	The observable physical characteristics or traits of an organism, determined by its genotype and environment.
pollen	Fine powder containing the male gametes (sperm cells) of seed-producing plants.
pollinations	The transfer of pollen from the male part of a plant (anther) to the female part (stigma).
recessive allele	An allele that is only expressed in the phenotype when two copies are present (homozygous).
codominance	A condition in which both alleles for a gene are fully and equally expressed in the phenotype of the heterozygote (e.g., a cow with both red and white hairs).
incomplete dominance	A pattern of inheritance where the phenotype of a heterozygote is an intermediate blend between the two homozygous phenotypes (e.g., red and white flowers producing pink offspring).
polygenic characteristic	A trait that is controlled by the interaction of multiple genes, often resulting in a wide range of phenotypes (e.g., human skin color or height).
