NGSS.HS-LS3-1

NGSS.HS-LS3-2

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

• co-dominant allele

• recessive allele

• dominant allele

• multiple alleles

NGSS.HS-LS3-1

An allele that is masked when a dominant allele is present.

• dominant allele

• recessive allele

• co-dominant allele

• multiple allele

NGSS.HS-LS3-1

Having two identical alleles for a trait.

(Ex: HH or bb)

• heterozygous

• homozygous

• dominant

• recessive

Having two different alleles for a trait.

(Ex: Tt)

• dominant

• recessive

• homozygous

• heterozygous

An organisms genetic makeup, or allele combinations.

(Ex: Aa, BB, ff)

• phenotype

• karyotype

• genotype

• Haplotype

The physical traits that appear in an individual as a result of its genotype.

(Ex: straight hair, curly hair, or wavy hair)

• karyotype

• genotype

• haplotype

• phenotype

The ratio of phenotypes that could appear in offspring:

(Ex: 3:1)

• phenotypic ratio

• karyotype

• mutation ratio

• genotypic ratio

The ratio of genotypes that could appear in offspring.

(Ex: 2:1:1)

• karyotypes
