Cross involving red and white flowers producing pink flowers demonstrates which heredity pattern?

• A. incomplete dominance
• B. mendel's law of segregation
• C. mendel's law of independent assortment
• D. sex linkage

Answer: (A)

Red and white flowers producing pink offspring show incomplete dominance: neither allele is fully dominant, so the heterozygous genotype yields an intermediate phenotype. The red allele and the white allele both contribute, giving pink flowers in the offspring of a red x white cross. Mendel's laws describe how alleles separate and assort during reproduction, but they don’t explain an intermediate color. Sex linkage involves genes on sex chromosomes and isn’t involved here. So the pink offspring illustrate incomplete dominance.
