Dominance Of Alleles Worksheet. The quiz tests you on basic concepts regarding dominant and recessive alleles. Alleles are components of genes that help determine physical characteristics.
Many other genes have multiple alleles, including the human genes for blood type.. The allele for black is B and the allele for white is W. Incomplete Dominance. plant (RR) breeds with a White flowered plant (WW).
Students describe an inherited trait and compare incomplete dominance, co-dominance, and multiple alleles.
In a certain fish, blue scales (BB) and red scales (bb) are codominant.
Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance. In some chickens, the gene for feather color is controlled by codominance. Since orange is a blend of red & yellow, it's incomplete dominance.
