DRAW IT A pea plant heterozygous for inflated pods (Ii) iscrossed with a plant homozygous for constricted pods (ii).Draw a Punnett square for this cross to predict genotypic andphenotypic ratios. Assume that pollen comes from the ii plant
Make a cross of four o’clock plant (Mirabilis jalapa L.) with red and white flowers. Get the F1 and F2 (by selfing F1), genotypic and phenotypic ratios. Show the phenotypic ratio by means of color.
In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a).Another gene has a recessive allele wx that results in waxy starch, as opposed to normal starch(Wx). The two genes segregate independently. An Aa WxWx plant is testcross. What are thephenotypes and relative frequencies of offspring?

- 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?arrow_forwardMore Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?arrow_forwardMore Crosses with Pea Plants: The Principle of Independent Assortment Think about this one carefully. Albinism and hair color are governed by different genes. A recessively inherited form of albinism causes affected individuals to lack pigment in their skin, hair, and eyes. In hair color, red hair is inherited as a recessive trait and brown hair is inherited as a dominant trait relative to red hair. An albino woman whose parents both have red hair has two children with a man who is normally pigmented and has brown hair. The brown-haired partner has one parent who has red hair. The first child is normally pigmented and has brown hair. The second child is albino. a. What is the hair color (phenotype) of the albino parent? b. What is the genotype of the albino parent for hair color? c. What is the genotype of the brown-haired parent with respect to hair color? Skin pigmentation? d. What is the genotype of the first child with respect to hair color and skin pigmentation? e. What are the possible genotypes of the second child for hair color? What is the phenotype of the second child for hair color? Can you explain this?arrow_forward
- More Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?arrow_forwardCrossing Pea Plants: Mendels Study of Single Traits Wet ear wax (W) is dominant over dry ear wax (w). a. A 3 : 1 phenotypic ratio of F1 progeny indicates that the parents are of what genotype? b. A 1 : 1 phenotypic ratio of F1 progeny indicates that the parents are of what genotype?arrow_forwardFigure 8.9 In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?arrow_forward
- Crossing Pea Plants: Mendels Study of Single Traits An unspecified characteristic controlled by a single gene is examined in pea plants. Only two phenotypic states exist for this trait. One phenotypic state is completely dominant to the other. A heterozygous plant is self-crossed. What proportion of the progeny of plants exhibiting the dominant phenotype is homozygous?arrow_forwardCrossing Pea Plants: Mendels Study of Single Traits Suppose that organisms have the following genotypes.

In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b.

- Crossing Pea Plants: Mendels Study of Single Traits If you are informed that tune deafness is a heritable trait, and that a tune deaf couple is expecting a child, can you conclude that the child will be tune deaf?arrow_forwardIn 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?arrow_forwardIn cucumbers, orange fruit color (R) is dominant over cream fruit color (r). A cucumber plant homozygous for orange fruit is crossed with a plant homozygous for cream fruit. The F1 are intercrossed to produce the F2. Q.
