Natural selection, adaptations, genetic variation, and population evolution are all related in terms of changes in phenotypes ov

er
time. Evaluate which statement appropriately describes the relationship between the concepts of natural selection, adaptations,
genetic variation, and population evolution and select the best choice.
A)
8)
Genetic variation exists in a population. Some of the genetic variation
results in different phenotypes. The phenotypes that enhance survival are
called adaptations. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Adaptations exist in certain individuals in a population. The increase in
adaptations causes an increase in genetic variation. The adaptations that
enhance survival lead to larger populations, which further increases
genetic variation. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Genetic variation is high in a population, but random events cause it to
decrease. Populations with fewer individuals and lower genetic diversity
are able to undergo natural selection when selective pressures are high.
The increase in selective pressure causes an increase in adaptations that
are better suited for survival This results in an evolutionary change of a
population
Selective pressures exist in nature and cause changes in a population.
Populations with high selective pressures have higher rates of genetic
change, leading to an increase in genetic variation, Increased genetic
variation leads to some individuals having well-suited adaptations. The
presence of these new adaptations is evidence that the population has
changed, or undergone evolution

Free_Kalibri [48]

Answer:

a) the selection intensity is 21bushels/acre

b) the response to selection is 12bushels/acre

c) The heritability is 0.57 (two decimal places)

Explanation:

Given:

mean grain yield population=72bushels/acre

mean grain yield selected individuals=93bushels/acre

mean grain yield new population=84busgels/acre

a) The selection intensity is given by:

SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre

b) The response to selection is:

RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre

c) The heritability of grain yield is:

H=RS/SI=12/21=0.57
