In which of the following statements are the HardyWeinberg c

In which of the following statements are the Hardy-Weinberg conditions NOT being violated?

Solution

Answer: e) In all statements the Hardy-Weinberg conditions are being violated

Answer:

Hardy and Weinberg described that all the possible genotypes for a gene with two alleles. The population is not surfacing due to any of the conditions that disturb Hardy-Weinberg equilibrium would be sufficient for the Hardy-Weinberg equation to accurately predict genotype frequencies from allele frequencies as described below. The binomial expansion representing this is, p2 + 2pq + q2 = 1.0

Where,

p2 = proportion of homozygous dominant individuals

q2 = proportion of homozygous recessive individuals

2pq = proportion of heterozygotes.

The five principles to attain equilibrium of HW are as described below

1. No mutations

2. No natural selection

3. Very large population size

4. Radom mating

5. No immigration or emigration i.e. population must be isolated therefore allele frequencies are the same in males and females

In case, if the high migration occurs into or out of the population, then founder effect and bottle neck effect occurs and followed by changes in allele frequencies result in evolution of new species occurs.

There has no selection took place, in the given example, i.e. some moths on a tree are easier to see due to their lighter color and therefore are eaten by predators more often. There was no gene flow in the given example, of global warming, in which a river has dried up, allowing two different rabbit populations to mate with one another, whereas they were isolated before. The conversion of quality habitat into farmland has greatly depleted the greater prairie chicken populations and, as a result, their genetic diversity in which, genetic diversity occurred therefore, these statements are the Hardy-Weinberg conditions being violated

Bottlenecking ---> the conversion of quality habitat into farmland has greatly depleted the greater prairie chicken populations and, as a result, their genetic diversity.

Random mating happened in the given example, so that Hardy -Weinberg conditions being violated, because male elephant seals show aggression toward other males, resulting in dominant males with several females and other males are mating with few or no females.

For example, inbreeding occurred in the descendants of 20 survivors after severe natural calamities on the Eastern Caroline Islands resulted in microevolution of new Pingelapese population evolved with different genetic alleles popularly exhibited achromatopsia, color blindness. Therefore, a new population of has evolved due to genetic drift and founder effect within the same population after a natural calamity.

No, it is not true, because evolution is not solely depends on the individual financial situations but it evolution is mainly depends on the \"environmental factors\", mutations in the individual cellular genome or migration or genetic drift. Individuals often develop favorable traits via natural selection & genetic variations in the successive generations with evolution of new traits in the new species as an evolutionary adaptation to attain adequate offspring fitness and to struggle for the existence. Therefore, poorer individuals having more children than their effluent counterparts are not leading to continuing evolution in the new human species
