Incomplete dominance in plants
WebNov 29, 2016 · Answer: Incomplete dominance is a type of interaction takes between two different alleles of a gene in which one allele can not express itself completely over the other allele.. It results in the production of third phenotype which is usually the intermediate of the two parental traits. For example, when plant bearing red colored (dominant trait) … WebIncomplete dominance. Two alleles may produce an intermediate phenotype when both are present, rather than one fully determining the phenotype. Codominance. Two alleles may be simultaneously expressed when both are present, rather than one fully determining the phenotype. Pleiotropy.

WebYet another example of incomplete dominance in plants is that of Mirabilis jalapa, a.k.a. the four o’clock flower or marvel of Peru. As with snapdragons, even in this plant the resultant species is pink in color when a red-flowering variety … WebMay 9, 2024 · Incomplete dominance: A dominant and a recessive allele produce an intermediate trait because the dominance of the dominant allele is incomplete and the recessive allele influences the trait. For example, a plant with a dominant red flower allele and a recessive white flower allele might produce pink flowers.
WebIncomplete dominance is also referred to as semi-dominance and partial dominance. Mendel described dominance but not incomplete dominance. Had he worked with Mirabilis jalapa rather than pea he would have pondered the cross of a plant with red flowers by one with white flowers. WebIncomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. Co-dominance can occur because both the alleles of a gene are dominant, and the traits are equally expressed.
WebProblem 9: Incomplete dominance In Mendel's experiments, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the result of crossing two Tt plants? A. 1/4 would be tall; 1/2 intermediate height; 1/4 short B. 1/2 would be tall; 1/4 intermediate height; 1/4 short.
