When the dominant allele does not completely mask the effect of the recessive allele in the heterozygote it is called polygenic dominance incomplete dominance dominance corecessive codominance?
Incomplete dominance.
When an offspring receives a dominant gene from one parent and a recessive gene from another parent what type of traits show up in the offspring?
The current school of thought is that a dominant gene needs only a single copy to express its coding where as a recessive gene needs two copies of itself. The different forms of a gene are called alleles. Each parent contributes an allele. For example brown eyes and blue eyes. A blue eyed person would have two blue eye genes. A brown eyed person would have at least one brown eyed gene and either a blue or brown eyed companion. Hence two blue eyed people should only have blue eyed children. Two brown eyed people could possibly have either blue or brown eyed children. Science is discovering that genes interact in very complex ways. There is dominance, recessive, codominance, corecessive, and interactions between multiple genes to produce an outcome. While the reporting of DNA research and discoveries may make it seem we have an understanding of how genes work the reality is that the study of DNA and its functions is still in its infancy.
