0% B)25% C) 50% D) 75% E) 100% Show Punnett square and explanation. If a red flowered plant is crossed with a white flowered one and the offspring produces pink flowers. What type of inheritance does this represent? sex linked B. multiple allele C incomplete dominance D. environmental effect E. partial inheritance 2) If a man and a woman of no rmad skin color have an albino child (aa) hat are the genotypes of the parents? A). AA and Aa B). Aa and Aa C). AA and AA 22 What is the probability that their next child will have normal skin color? A) 0% B)25% C)50% D) 75% E) 100% EN 23 Consider the alleles involved in polygenic traits such as human height. Is the concept of dominance relevant to these alleles? Why or why not? A. Yes. the dominant trait alleles confer the highest values for the trait and the highest fitness. B. Yes-The dominant alleles are the most common C. No-the alleles in polygenic traits are always co-dominant D. No-dominance can occur only in discrete traits 24 Sickle cell anemia is a genetic disorder in which the genotype of normal persons is HbNHbA.If the level of blood oxygen drops below a certain level, in a person with the Hbs/Hbs genotype, the red blood cells form sickle or crescent shapes. These calls do not carry enough oxygen to tissues causing damage. The sickle cell gene is pleiotropic, What does that mean? 2 A. It means that several genes are interacting B. it means that one genes can have many effects C. it means that two alleles both partially express themselves in the phenotype 29 Persons that are HbA/Hbs are said to be- A. homozygous for the trait B. heterozygous for the trait so they have the condition C. heterozygous for the trait and therefore carriers D. able to produce enough normal hemoglobin to appear normal but their red blood cells will sickle if they are in a low oxygen situation.

    II. MONOHYBRID PROBLEMS WITH INCOMPLETE DOMINANCE 8. Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R R are red-flowered, those that are heterozygous (R W ) are pink, while those with the (WW ) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1? __________________________________________________________ b. What...
