Detailed explanation-1: -The resulting offspring have pink flowers. What term describes the dominance of this trait? Explanation: A phenotypic “blending” of two traits is referred to as incomplete dominance, indicating that neither trait is truly dominant over the other.

Detailed explanation-2: -The crossing over between two pink flowering plants results in the partial expression of both alleles, such as red and white, observed in the next plant generation. These two different alleles are a heterozygous condition representing a concept of genetics called incomplete dominance or semi-dominance.

Detailed explanation-3: -Answer and Explanation: If two hybrids are crossed, meaning two heterozygous pink flowers, the chances that the offspring will have pink flowers is 50%. There will also be a 25% chance of a homozygous dominant red flower. Any 25% chance of a homozygous recessive white flower.

Detailed explanation-4: -The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles.
