Mendelian Genetics

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

The instructions of this allele are covered up by the other allele in a homologous pair. Symbolized by a small letter.

• Homozygous

• Dominant

• Recessive

The "Father of Genetics"

• Isaac Newton
• Gregor Mendel
• Albert Einstein
• Robert Hooke

The hidden trait.  You need two of these alleles for the trait to show.

• Dominant
• Recessive
• Hidden
• Overt

If a trait is homozygous the letters are the 

• Same
• Different

If you are homozygous recessive, the genotype would be 

• AA
• aa
• Aa

If you are homozygous dominant, the genotype would be 

• AA
• aa
• Aa

If you are heterozygous, your genotype would be

• AA
• aa
• Aa

The observable traits of an organism are known as its

• allele
• dominance
• phenotype
• genotype

Each parent contributes one of the genes for a particular trait. The genes of the pair are called:

• variables
• gametes
• hybrids
• alleles
