Mendelian Genetics

Different variation of a single gene (example: tall and short) is

• Allele

• Trait

• Phenotype

• Genotype

Having two identical alleles for a particular gene (aa)

• Phenotype

• Homozygous

• Heterozygous

• Dominant

Trait is expressed, even if there is only one copy of this trait

• Heterozygous

• Recessive

• Dominant

• Test-Cross

Physical characteristics of an organism (what it looks like)

• Trait

• Phenotype

• Recessive

• Genotype

Each allele on a gene will separate independent of each other

• Law of Independent Assortment

• Rule of Addition

• Allele

• Locus

A genetically determined characteristic of an individual

• Homozygous

• Law of segregation

• Allele

• Trait

• Test-cross

• Rule of multiplication

NGSS.HS-LS1-1

Having two different alleles for a particular gene (Aa)

• Heterozygous

• Recessive

• Trait

• Homozygous

Probability that 2+ independent events will occur together in a specific combination (A and B will happen)

• Rule of Multiplication

• Dominant

• Law of Probability

• Locus

Calculations that determine the likelihood that A will be passed down from parent to offspring

• Trait

• Law of Probability

• Homozygous

• Law of Independent Assortment
