Karyotype/Genetics

Two different alleles in a gene (ex. Hh or Rr)

• purebred

• homozygous

• hybrid

• recessive

Alleles in a gene pair that are identical

• purebred

• homozygous

• hybrid

• phenotype

The observable or expressed form of a trait. What you physically see.

• Phenotype

• Genotype

• Punnett Square

• Allele

The form of an allele that is EXPRESSED when the gene pair is heterozygous; can hide or cover up the other form

• heterozygous

• dominant

• recessive

• purebred

The form of an allele that is EXPRESSED when the gene pair is homozygous and recessive

• heterozygous

• dominant

• recessive

• allele

Alleles in a gene pair that are different

• Homozygous

• Purebred

• Phenotype

• Heterozygous

The exact form of the alleles in a gene pair; represented using letters (ex. YY, Yy, yy)

• genotype

• phenotype

• Punnett Square

• recessive

Use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses

• alleles

• Punnett Square

• recessive

• dominant

Pictures of the arrangement of all the chromosomes an organism contains. Can you if there are any chromosomal abnormalities.

• Punnett Square

• DNA replication

• Karyotype

• Purebred

The form of a specific gene (ex. R, h, P, q)

• RNA

• dominant
