Mendelian Genetics

A feature regulated by a set of genes (allele) passed on

from parents to offspring.

• Heterozygous

• Mendel

• Chromosome

• Traits

The instruction of one allele covers up the instruction

of the other allele in a homologous pair. Symbolized by a capital letter.

• Recessive Allele

• Dominant Allele

• Heredity

• Trait
