What law states that in Tt the person will only show the dominant allele

• law of segregation
• law of independent assortment
• law of dominance
• law of punnett squares

the passing of genetic traits from parent to offspring.

• heredity
• trait
• gene
• allele

having two of the same genes for the trait (sometimes called purebred).

• homozygous
• hetrozygous
• protein
• chromosome

having two different genes for a trait (sometimes called hybrid).

• protein
• homozygous
• heterozygous
• genotype

A chart that traces the history of traits in a particular family

• DNA
• pedigree

• variation

Organisms that always produce offspring with the same traits are known as

• true breeding

• hybrid

• dominant trait

• recessive trait
