Answer:

OB T, B t, b T, b t

Explanation:

By using FOIL method, first two allele of each genotype combine with each other, then first allele of the first genotype and second allele of the second genotype join together. After that, second allele of the first genotype join with the first allele of the second genotype and at last, second allele of first genotype fuse with second allele of the second genotype. Hence, gametes i. e. OB T, B t, b T, b t are produced.

The row of energy in a grassland ecosystem is shown

bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

N a pond, tadpoles eat algae and fish eat the tadpoles. around the pond, grasshoppers eat grass and, at night, are preyed upon b

Dima020 [189]

I believe that in this community the tadpoles are: the primary consumers. A n ecological community is the set of all populations of all species found in a given place. Primary consumers are mainly herbivores which feed on plants; which are the primary producers of all the energy in an ecosystem. In this case the tadpoles eat algae (primary producer) thus they are primary consumer.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for

Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

EeWw x EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>
