If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?
NNADVOKAT [17]

Answer:

<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.

timurjin [86]

A marine biologist is examining the effects of oil pollution on a population of birds known as seagulls (Larus canus). She is particularly concerned that oil pollution may reduce the number of eggs raised in a seagull nest. During one breeding season, she counted the number of eggs present in a sampling of six seagull nests near each of the 14 refineries throughout the state. She discovered that seagulls laid and raised an average of four eggs per season. To confirm her hypothesis, the researcher must now examine seagull nests that have not been exposed to oil pollution. The researcher believes she is correct, and so expects to find D) 4-6 eggs per nest.
