An organism with 2 different alleles for a trait is called a ______.

heterozygous

300

The tool used to show all of the possible outcomes of a genetic cross.

Hair color is an example of which type of inheritance, when groups of alleles control the trait?

polygenic inheritance

400
This occurs when 2 traits are neither dominant nor recessive, both show up.
co-dominant / codominance
