Genetics Test

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

What is a phenotype

• The genetic make up (code)
• The physical trait

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
• homozygous
• heterozygous
• genotype
