A red flowered plant was crossed with a blue flowered plant and produced all purple flowered plants. When the purple flowered plants were crossed with each other they produced 5 red plants, 5 blue plants, 20 deep purple plants, 20 light lilac plants, and 30 purple plants How many genes are involved in the color production? Assume that red color is caused by an A allele and blue color by a B allele and determine the likely genotype of the plants in the F2 generation

selves in the offspring. The crosses are lled ssed differently in homozy- heterozygous individuals. This produces a con- dition called incomplete dominance. In such cases, both worked out in the same manner as indicated previously, but heterozygous offspring exhibit a phenotype interme- diate between that of the homozygous individuals. Some examples follow. Activity 2 Working Out Crosses Involving Incomplete Dominance 1. The inheritance of flower color in snapdragons illustrates the principle of incomplete dominance. The geno-type RR is expressed as a red flower, Rr yields pink flowers, and rr produces white flowers. Work out the following crosses to determine the expected phenotypes and both genotypic and phenotypic percentages. % of each phenotype: 2. In humans, the inheritance of sickle cell anemia/trait is deter- mined by a single pair of alleles that exhibit incomplete domi- nance.

Genetics 181 Rule of Incomplete Dominance When two different pure-breeding strains are crossed, and their offspring show a blending of phenotypes, then neither allele is dominant. This is easily recognized when the phenotype is somewhere between two extremes. Counting the parents, there are three phenotypes (black, white, grey) being expressed in these flowers instead of only two, and that third phenotype is intermediate between the other two. This heterozygous condition is called incomplete dominance. 1. On the chart you did earlier, which of the three hair types (wavy, curly, or straight) represents incomplete dominance-the blended heterozygous condition? 2. You cross a herd of red cattle with white cattle and all of the calves appear to be roan (reddish white). Is this an example of incomplete dominance? How do you know? 3. You cross a blue flowering pea plant with a white flowering pea plant and all of the offspring are blue flowered. Is this an example of incomplete dominance? How…
11 Normal No Spac. Styles Paragraph Inheritance APPLICATION Imagine that you are interested in developing a new tomato plant that will inchude the large size and sweetness from one parent and yellow color from another parent. The first parent plant has bland-tasting small yellow tomatoes and the other parent has sweet-tasting large red tomatoes. The chromosomes and alleles of the two plants are shown below. Plant #1: Bland (B), Small (1), Yellow (r) Plant #2: Sweet (b), Large (L), Red (R) R 1 r R Think about what you learned about inheriting traits from the lab to answer these questions. 1. Explain (in sentence form) why it is or is not possible for any of the offspring of these parents to have the sweet gene expressed in its phenotype. To illustrate your explanation, you may use a diagram or use the Punnett squares below to show the genotypes of the possible offspring. Include a percent chance in your answer. 2. Explain whether or not it is possible to create a tomato plant with…
INCOMPLETE DOMINANCE. All of the traits in these problems show incomplete dominance. Work these as you did the other monohybrid crosses, but interpret your results with the rules for incomplete dominance. 1. In snapdragons, flower color shows incomplete dominance. Red color is dominant to write color. What kind of offspring could result from Parent 1 being heterozygous and Parent 2 have a white flower color? Trait:
Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
