DNA
The abbreviation for deoxyribonucleic acid.
Allele
A member of a gene pair that determines a specific trait.
Mendel
The Father of Genetics.
Hybrid
This has genes that are different for a trait, such as Tt.
Genotype
The actual gene makeup of an organism.
Traits
Physical characteristics of an organism that are passed down from one generation to
the next.
Incomplete Dominance
A condition in which neither of the two
genes in a gene pair masks the other.
Chromosomes
Rod-shaped structures found in the nucleus of every cell in an organism.
Dominant
Trait is expressed when two different genes for the same trait are present.
Phentype
The physical appearance of a trait.
Pea Plants
Mendel experimented with:
Homozygous
A gene pair consists of two dominant alleles or two recessive alleles
Law of Segregation
This Law states one gene from each gene pair separates to each sex cell
Genes
The traits of an organism are controlled by its:
Punnett Square
Achart used to show the possible gene combinations in
across between two organisms.
Heterozygous
A gene pair that consists of a dominant allele and a recessive allele
First Filial
This generation is the offspring of the P, or parental, generation.
Geneticist
A scientist who studies heredity.
Recessive
This trait seems to disappear when two different genes for the same trait are
present.
Parent
Organisms inherit genes in pairs, one from each:
Genetics
The study of heredity.
Law of Independent Assortment
This Law states that each gene pair is inherited
independently of the gene pairs for other traits.
