Figure 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?

Expert Solution & Answer

Summary Introduction

To analyze:

If the parent plant is homozygous dominant or heterozygous.

Introduction:

An organism is known as homozygous dominant when it carries two copies of same dominant allele and when it carries two copies of the same recessive allele, then it is called as homozygous recessive. In case of heterozygous organisms, two different alleles of a gene are present.

Explanation of Solution

Given:

Concepts of Biology, Chapter 8, Problem 1ACQ

According to the figure, Punnet square depicts the cross between plants with yellow and green seeds. There is a cross between the true-breeding parent (P) plantswhich produce F1 heterozygotes and are capable of self-fertilization. This self-cross of the F1 generation can be used for analysis with the Punnet square for predicting the genotype of the F2 generation. If the inheritance pattern of the dominant and recessive is provided then, the genotypic and phenotypic ratios can be determined.

Here, the pea plants having round peas(R) are dominant to the wrinkled peas(r). A test cross between a pea plant with the wrinkled peas having genotype (rr) and an unknown genotype having round peas. The progenyhas three plants with round peas. From this data,it cannot be surely concluded if the given plant is homozygous or heterozygous because the data set given is quite small. Due to a random chance, the three plants have acquired the dominant gene only even if the recessive gene is present.

Conclusion

Thus,from this data, we can't conclude if the given plant is homozygous or heterozygous because the data set given is quite small.

In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. What will be the phenotypic ratios in the F2? 2. If an F1 plant is backcrossed with the bitter, yellow-spotted parent, what phenotypes and proportions are expected in the offspring? 3. If an F1 plant is backcrossed with the sweet, non-spotted parent, what phenotypes and proportions are expected in the offspring? 4. In cats, curled ears (Cu) result from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1…

In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp

In corn, two independent, recessive nuclear genes, japonica (j) and iojap (ij), produce variegation (green and white striped leaves). Matings between individuals heterozygous for japonica always produce 3 green:1 striped individuals regardless of how the cross is performed. You have a variegated plant that could be either jj or ijij . What cross can you make to determine the genotype of this plant, and what results do you expect in the F1 generation in each case?
