Heredity Quiz

An organism’s genetic makeup, or combination of alleles.

• purebred
• phenotype
• codominance
• genotype

An organism’s physical appearance, or visible traits.

• genotype
• dominant trait
• phenotype
• hybrid

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

• phenotype
• homozygous
• heterozygous
• genotype

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

• homozygous
• hetrozygous
• protein
• chromosome

An allele whose trait always shows up in the organism when the allele is present.

• recessive allele
• dominant allele
• codominant allele
• heterozygous allele

Having two different alleles for a trait (example Hh):

• homozygous
• heterozygous
• dominant
• purebred

Having two of the SAME alleles for a trait (example HH or hh):

• homozygous
• heterozygous
• recessive
• dominant

What is heredity?

• how different genes and traits are passed down from parents to children
• how different genes and traits are passed down from children to parents
• how traits are identical to parents
• how traits are different between siblings 

What is a gene?

• an entire chromosome that  codes for a trait
• a piece of clothing
