phenotypes that shows both traits

The different forms of a gene are called

• traits

• pollinations

• alleles

• hybrids

Roan cattle show codominance for the color of their hair. There are alleles for red hair and white hair. What would you expect a heterozygous roan bull to look like if the trait showed incomplete dominance instead?

• It would be red

• It would be white

• It would be spotted

• It would be pink

Situations in which one allele for a gene is not completely dominant over another allele for that gene are called

• multiple alleles

• incomplete dominance

• polygenic inheritance

• multiple genes

In rabbits, there are four different versions of the gene for coat color. What pattern of inheritance is this?

• incomplete dominance

• polygenic inheritance

• codominance

• multiple alleles
