Question
In a population of pea plants, some plants have yellow seeds and others have green seeds. The gene for seed color has two possible alleles. One allele is for yellow seeds (Y), and the other allele is for green seeds (y).Consider this information about a certain pea plant in the population:The plant has yellow seeds.The plant has one allele for yellow seeds, and one allele for green seeds.What phenotype does this plant have for the seed color trait?Choose 1 answer:Choose 1 answer:(Choice A) YYAYY(Choice B) YyBYy(Choice C) yellow seedsCyellow seeds(Choice D) green seedsDgreen seeds
Solution
To determine the phenotype of the pea plant for the seed color trait, follow these steps:
-
Identify the alleles: The plant has one allele for yellow seeds (Y) and one allele for green seeds (y).
-
Determine the genotype: The genotype of the plant is Yy.
-
Understand dominance: The allele for yellow seeds (Y) is dominant over the allele for green seeds (y).
-
Determine the phenotype: Since the yellow allele (Y) is dominant, the presence of one Y allele will result in yellow seeds.
Therefore, the phenotype of the plant is:
(Choice C) yellow seeds
Similar Questions
A particular pea plant has one allele for a tall stem (T) and one allele for a short stem (t). By observing it, you can see that it has a tall stem as well as many other different traits.Using this example, explain the difference between phenotype and genotype. Which one can be observed? Which one helps to determine the other?
Genes are segments of DNA that determine the phenotype of an individual. Pea colors can be yellow or green. When two plants that produce yellow peas were crossed, the offspring produced green peas. This is because the parents were for pea color. Because there are only two options for pea color, the plants’ pea color is a case of
In a test cross, a homozygous recessive pea plant with green seeds is mated with a yellow-seeded plant of unknown genotype. If all the progeny have yellow seeds, then the genotype of the yellow-seeded plant is
In the garden peas of one pair of alleles controls the height of theplant and a second pair of alleles controls flower colour. Theallele for tall (T) is dominant to the allele for dwarf (t) and theallele for purple flower colour (P) is dominant to the allele forwhite (p).a.
