Genotype refers to the ...

• physical expression of the genes
• the possible combination of alleles in a gene
• whether an allele is dominant or recessive
• how an organism will appear

Squidward has light blue skin, and his genotype for this trait is Bb. Would Squidward be considered a purebred or hybrid for light blue skin?

• Purebred
• Hybrid

An offspring will receive how many alleles from each parent to determine a specific trait?

• one
• two
• three
• five

Having two of the same genes for the trait (sometimes called purebred).

• homozygous

• hetrozygous

• protein

• chromosome

Having two different genes for a trait (sometimes called hybrid).

• protein
