Genetics Intro

a chart that shows all the possible combinations of alleles that can result from a genetic cross

• punnett square

• probability

• pedigree

• genetics

two different alleles for a trait (Rr)

• homozygous

• heterozygous

• purebred

• phenotype

NGSS.HS-LS3-2

two of the same alleles for a trait (RR or rr)

• homozygous

• heterozygous

• hybrid

• phenotype

an organism's physical appearance or visible traits like eye color

• genotype

• phenotype

• hybrid

• heredity

an organism's genetic makeup or the allele combination (what the letters represent RR, Rr, rr)

• genotype

• phenotype

• heterzygous

• homozygous

NGSS.HS-LS3-2

an organism that has two different alleles or heterozygous for a trait (Rr)

• hybrid

• purebred

• phenotype

• homozygous

an allele that is hidden when a dominant allele is present

• Allele

• Recessive Allele

• Dominant Allele

• Genotype

an allele whose trait always shows up in the organism when the allele is present

• recessive allele

• dominant allele

• genotype

• phenotype

different forms of a gene (can be dominant or recessive)

• trait

• heredity

• genetics

• alleles

a segment of DNA on a chromosome that codes for a specific trait

• Gene

• Allele

• Phenotype

• Fertilization
