Chromosomes and Inheritance (meiosis)

Mr. Tudor 8th Grade Science

Relationships: Chromosomes, Genes & Inheritance

• Mendel showed genes exist (he called them factors)

• Walter Sutton (1900's) hypothesized chromosomes were the key to unlocking trait similarity.

Chromosome Pairs

• Body Cells: Specialized cells in the body.

• Sex Cells: Egg (ovum)/Sperm in animals. Ovule/pollen in plants.

Homologous Chromosomes

The pair-off based on being similar!

Homologous Pairs

• Genes Line up!

• See the alleles from each parent?
