- In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross: P1: AABBCCDDEE aabbccddee F1: AaBbCcDdEe (self-cross to get F2) What is the chance of getting an AaBBccDdee individual in the F2 generation?Do a punnet square to find the possible genotypes and phenotypes of the F1 generation when a plant that is homozygous recessive for pod color and heterozygous for pea shape is crossed with a plant that is heterozygous for pod color and homozygous dominant for pea shape. Dominant for pod color = G (green) Recessive for pod color = g (yellow) Dominant for pea shape = R (round) Recessive for pea shape = r (wrinkled) P1: GG X Rr Gg X RR
- You cross a purple flower plant (Ww) with a white flower plant (ww). You can assume W is dominant and we have complete Dominance with 100% Penetrance and Expressivity. W=Purple color w=White color W is dominant Ww ww If you get 120 plants from this cross, how many do you expect to have white flowers? Provide integer without any spacesPea PlantsIn pea plants, a round-seed shape (R) is dominant over a wrinkled-seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? Show all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.The following is totally made up (not real). unicorn mane color shows incomplete dominance. R codes for a red mane. r codes for a blue mane.

- You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob. Crossing the plant with heterozygous purple flowered pea plant (Pp) Crossing the plant with homozygous dominant purple flowered pea plant (PP) d. Crossing the plant with a plant whose genotype is unknown e. Crossing the plant with homozygous recessive white flowered pea plant (pp)In pea plants, yellow seeds are dominant to green seeds. A heterozygous 2. yellow-seeded pea plant (Yy) is crossed with a plant that has green seeds (yy). Yellow Genotype Probability (%) Phenotype Probability (%) Seeds Y y y YY Yellow Seeds: y Yy Green Seeds: УУ metics Punnett Squares Green SeedsWe have crossed true-breeding flies today. Wild type to mutant. Their phenotypes were wt and vg se. (Let’s not worry about males and females for now, just assume both genes are autosomal, which is normal in a Mendelian experiment). The results of a cross are phenotypes. I will be asking you for numbers or a ratio of phenotype numbers you expect to see in the offspring from this cross. To answer this, you’ll need to start with the genotypes of parents, then write their gametes, then write the offspring genotypes, then get the phenotypes based on them. Predict the results of this cross: In case both mutations are recessive; In case both mutations are dominant; In case vestigial wings are recessive and the sepia eyes are dominant.
