Unit 3.1 Vocabulary Practice Variation of Traits

This is the genetic makeup of an organism. You can not always determine this by the appearance of an organism.

NGSS.HS-LS3-2

The observable alleles (traits or characteristics) of an organism. You can easily observe these if you examine the organism.

• Phenotype

• Genotype

• Heredity

NGSS.HS-LS3-3

This describes the transmission, or passing, or traits from one generation to the next.

NGSS.HS-LS3-2

This type of allele will only present in the organism if the organism inherited two copies of the allele.

• Recessive

• Dominant

• Heterozygous

These alleles will show in the organisms phenotype even if the organism only received one copy of the allele.

• Recessive

• Dominant

• Heterozygous

NGSS.HS-LS3-1

This term describes alleles that are a different form of a particular gene inherited from each parent. Example: Hh

• Homozygous

• Dominant

• Heterozygous

This term describes alleles that are the same form of a particular gene inherited from each parent. Example: HH

• Homozygous

• Recessive

• Heterozygous

This term describes the different forms of the same gene.

• Trait

• Punnett Square

• Allele

This tool is a grid that helps to show all allele combinations of gametes in a cross between parents where the genotypes are known. The results help predict probability of the offspring possessing certain alleles.

• Allele

• Trait Cross

• Punnett Square

This term is a genetically determined characteristic.

• Trait

• Allele

• Heredity
