A white mouse with red eyes is crossed with a black mouse with brown eyes. The white mouse is recessive for both of its traits. The black mouse is dominant for both of its traits.
This cross would be
BBEE x bbee
BBEe x BbEe
BbEE x BbEe
BBee x BBEE
A way to predict genetic probability using two different
sets of alleles on two different chromosomes.
Co-Dominance
Incomplete Dominance
