What is the definition of an allele?

• An allele is a variant of a gene.

  (variants = different types of something)

• An allele is the genetic makeup of an organism

  (organism = a living thing)

• An allele is synonym for a gene.

  (synonym = words meaning the same thing)

An allele whose trait only shows up when no dominant allele is present.

• hidden allele
• dominant allele
• recessive allele

What is the definition of homozygous?

• when both alleles are the same

• when it is neither dominant or recessive
