Q.
In heterozygotes both traits are expressed, for example breeding a white bear with a black bear results in offspring that have both black and white patches together.

Q.
A condition when the dominant allele does not completely mask the recessive. As a result some of the recessive trait will be observed in the phenotype. An example in plants may be color of flowers. The color red is dominant over the recessive color white. Pink flowers are a result of a blending of red and white.
