Monohybrid Problems with Incomplete Dominance 4. 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'R²) are pink, and those with the R°R² genotype are white. This is an example of incomplete dominance. (Note that superscripts are used rather than upper- and lowercase letters to describe the alleles.) a. If a white-flowered plant is crossed with a red-flowered petunia, what is the genotypic ratio of the F, offspring? - b. What is the phenotypic ratio of the F, offspring? . c. If two of the F, offspring are crossed, what phenotypes will appear in the F2 generation?. d. What will be the genotypic ratio in the F2 generation?.

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:

Incomplete Dominance 1. In snapdragons, red flower color (R) is incompletely dominant over white flower color (r).

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. Individuals homozygous for the sickling gene (s) have sickle cell anemia. In double dose (ss), the…
the progeny i each seehario. Q4. You conducted an experiment similar to Morgan's fruit fly but you used honey bee instead. You are thus following 2 genes, the wing size Long (L) and short (1) and body color Yellow (Y) and black (y). You crossed YyLI x yyll and obtained 4,000 offspring. You counted the offspring classes and found the following distribution as follows: 1200 YyLl individuals 1190 yyll individuals 800 Yyll individuals 810 yyLl individuals a) what is the phenotype of each class of offspring? b) Which classes are of the parental type and which are the recombinant types? c) What is the recombination frequency between both genes? d) What is the map distance in cM and in map units between both genes? When you counted the offspring, you also collected data on a third gene coding for antenna shape. The gene has 2 alleles in the population, bended antenna (B) and straight antenna (b). You found a distance of 13 cM between the gene for antenna shape and that for wing size, and 24…
Styles Editing The shapes and colors of radishes are controlled by two independent pairs of genes that show no dominance. The color may be red (RR), white (WW), or purple (RW). The shape may be long (LL), round (00), or oval (LO). Show a cross between a long, red radish and a round, white radish. Show the genotypes, the phenotypes and the probabilities of the first generation. If the offspring of the F1 generation are allowed 8. to self-pollinate, what types of offspring will be expected in the F2 generation?

Hello! I have a question. Question: “Match” each example under the correct type of dominance. (For matching I’ll list the numbers, and you can put the number with the correct type of dominance) 1. red rose + white rose= pink rose 2. white mouse + brown mouse = Brown and white dots 3. brown eyes + green eyes= brown eyes 4. straight hair + curly hair = wavy hair 5. dimples + no dimples = no dimples 6. green pea plant + yellow pea plant = yellow pea plant 7. red rose + white rose= red rose with white stripes Types of dominances: Complete dominance (Mendellian) Incomplete dominance Co-dominance
