Suppose that the "fabulous" phenotype is controlled by two genes, A and B, as shown in the diagram below. Allele A produces enou
vitfil [10]

Answer:

The expected ratio of the F_2 generation from F_1 generation will be

<u>9 "fabulous": 3 "smashing": 4 "plain" </u>

Explanation:

The expression of the phenotype will follow Mendel's Dihybrid cross.

plain→smashing

(only when allele A is present, which produces Enzyme 1)

smashing→fabulous

(only when allele B is present, which produces Enzyme 2)

Keeping the above statements in mind, in F_2 generation, only the genotypes having both A and B alleles will express phenotype "fabulous",as both Enzyme 1 and Enzyme 2 are required for that. The genotype having at-least one A allele and no B allele will produce the phenotype "smashing", as Enzyme 1,produced by allele A, will convert "plain" into "smashing". Hence, the dihybrid cross will as in the attachment.

A population that is decreasing in size will have an age-structure histogram shaped like a(n): 1) inverted pyramid, with a narro
lawyer [7]

The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.

The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.

In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.
