Which term is correctly matched with the description?

Incomplete dominance occurs when traits blend producing a third phenotype.

Co-dominance occurs when two traits blend together to form a new phenotype.

Human skin color is an example of codominant trait.

Human blood type is not an example of multiple alleles.

T2 - Which observation of dihybrid crosses led to Mendel's law of independent assortment

Particular individual traits persisted for many generations

Many combinations of traits were always inherited together

Some combinations of traits were not passed onto offspring

Fruit flies can have red eyes or white eyes. If a heterozygous red-eyed fly and a homozygous white-eyed fly produced 50% red-eyed offspring and 50% white-eyed offspring, which of the following is true of the traits?
