what is Homogeneous?
The prefix homo means “same.” An individual who is homogeneous has two genes that are the same—BB or bb.
The prefix homo means “different.” An individual who is homogeneous has two genes that are different—Bb.
The prefix hetero means “Codamince.” An individual who is heterogeneous has one that are different—Bb.
The prefix Generous means “different.” An individual who is heterogeneous has two genes that are different—Bb.
The prefix hetero means “ (a) .” An individual who is heterogeneous has two genes that are different—Bb.
You would identify the genotype of an individual who is Bb as “ (a) ,”
the genotype of an individual who is BB as “ (a) ,”

What is the meaning of Codominance?
Occurs when two traits are dominant at the Different Time. (Example: If someone has an A and b in their blood type, then they will have Ab blood since both are codominant.)
Occurs when two traits are Recessive at the same time. (Example: If someone has an A and b in their blood type, then they will have Ab blood since both are codominant.)
Occurs when two traits are dominant at the same time. (Example: If someone has an A and B in their blood type, then they will have AB blood since both are codominant.)
Occurs when two traits are heterogenous at the same time. (Example: If someone has an A and b in their blood type, then they will have Ab blood since both are codominant.)
