Mating is rarely random. Many organisms choose a mate for specific reasons - body size, coloration, antler size, feather length,

etc. Changes in allelic frequencies due to this non-randomness of mating is called Question 3 options: Hardy-Weinberg equilibrium. natural selection. genetic drift. gene flow.

Answer:

Natural selection

Explanation:

Sexual selection refers to the natural selection where the allele frequencies of a population are changed due to nonrandom mating between the individuals. Certain preferences for the mate by organisms result in sexual selection. It is mostly exhibited by females.

For example, peahen prefers the peacocks with elaborate tail features as their mate. The sexual selection also occurs when there is competition among the members of the same sex for a mate. This type of sexual selection is mostly exhibited by males and results in fighting and display.

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.

When does the chunk of ice have the most potential energy?
klasskru [66]

An enormous rift in one of Antarctica’s largest ice shelves grew dramatically over the past month, and a chunk nearly the size of Delaware could break away as soon as later this winter, British scientists reported this week.

If this happens, it could accelerate a further breakup of the ice shelf, essentially removing a massive cork of ice that keeps some of Antarctica’s glaciers from flowing into the ocean.

What usually causes creep?
notsponge [240]
Soil creep is the downward movement of soil, on a slope, caused by the force of gravity. A slow deformation of soil material over a prolonged period of time, from pressure and stress. Creep occurs when the friction from materials resisting gravity move against each other. Slope is a key cause of soil creep.
