Question

in the demo, the penny represents a recessive trait and the quarter a dominant trait. an organism with one of each trait is called which of these?

incompletely dominant
homozygous
heterozygous
sterile

Explanation:

• Incompletely dominant: Refers to a situation where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes. This is not relevant to having one dominant and one recessive trait.
• Homozygous: An organism with two identical alleles (either two dominant or two recessive). So it does not match having one of each trait.
• Heterozygous: An organism that has one dominant and one recessive allele. This fits the description of having one of each trait (dominant - quarter and recessive - penny).
• Sterile: Refers to an organism that cannot produce offspring. This has no relation to having one dominant and one recessive trait.

Answer:

heterozygous
