• a piece of RNA that provides instructions to make proteins

• a piece of the pie that results in the number 3.14

• a piece of a gamete that makes a protein synapsis

What word matches this definition,"is any of the alternative forms of a gene that may occur at specific locus.

• allele

• gene

• gamete

• dominant

The word homologous best fits which definition,

• two of the same alleles at a specific locus

• three of the same alleles at a specific locus

• one of the different alleles at a specific protein

• two of the different alleles at a specific locus

This word describes two different alleles at a specific locus.

• heterozygous

• homorzygous

• dominant

• allele

What is a genome?

• different alleles

This word mean that when it typically refers to the genetic makeup of a specific set of genes

• genotype

• phenotype

• allele

• gene

Phenotype refers to

• the physical characteristics, or traits, or set of traits

• the genetic makeup of an organism

• the different amount of alleles each organism will recieve

• the same number of physical features every organism will receive

Which word best fits this defintion, "allele that is expressed when two different alleles or two dominant alleles are present

• dominat

• gene

• trait

Recessive refers to as

• an allele that is expressed only when two copies are present

• an allele that is can only be expressed with one copy present

• a trait that is present throughout life
