WebScience. Biology. Biology questions and answers. 1. Flower color in snapdragons is due to a gene with incomplete dominance: CRCR plants have red flowers, CRCW have pink flowers, and CWCW plants have white flowers. What types and ratios of flower color are expected among the progeny of a cross of pink. Question: 1. WebOct 14, 2024 · This pattern of inheritance is described as incomplete dominance, meaning that one of the alleles appears in the phenotype in the heterozygote, but not to the exclusion of the other, which can also be seen. The allele for red flowers is incompletely dominant over the allele for white flowers.
Web54 Incomplete dominance: when traits blend Flower color in snapdragons. Mendel’s results in crossing peas, black vs brown fur color, and eumelanin production vs pheomelanin production all demonstrate traits are inherited as dominant and recessive.

Instead, a different phenotype is seen that is a combination of the phenotypes of the two alleles. An example of this is the pink flower color in snapdragons.
WebMar 5, 2024 · Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotypes of both parents; a completely dominant allele does not occur. For example, when red snapdragons (C R C R ) are crossed with white snapdragons (C W C W ), the F 1 hybrids are all pink heterozygotes for flower color (C R C …
WebJun 9, 2024 · Incomplete Dominance: One allele for a specific trait is not completely expressed over its paired allele. Using flower color in tulips as an example, the allele for red color (R) does not totally mask the allele for white color (r).
