A type of plant that produces red flowers is crossed with a plant that produces white flowers. The alleles for flower color exhibit incomplete dominance, and all of their offspring have pink flowers. If two of the pink-flowered offspring were crossed, which of the following ratios of red, pink, and white flowers would you find in their offspring? Answer 0% red : 100% pink : 0% white 25% red : 50% pink : 25% white 33% red : 33% pink : 33% white 50% red : 0% pink : 50% white

Answer: 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. Here, the dominant gene is not in a position to completely suppress the expression of the recessive gene. With the result, the heterozygous offspring will be phenotypically and genotypically different from either of the homozygous parent.
So, red 0% : pink 100%: white 0% .
