Explain the 6 steps of how Darwin theorized how the finches formed new species:
Scilla [17]
Overproduction
Most species produce more offspring than can survive.

Competition
Since living space and food are limited, organisms must compete for the necessities.

Variation
Differences between individuals in a population.

Adaptations
Any kind of inherited trait that improves an organism's chances of survival.

Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.

Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.

Ivenika [448]

One who researches 'botany' is called a 'botanist'. Botany is one of the world's oldest natural sciences. initially, Botany protected all plant-like organisms inclusive of algae, lichens, ferns, fungi, and mosses in conjunction with actual flowers.

Darwin understood the centrality of development in a deep and profoundly vital manner, both for animals and for flora. His notebooks document his cautious studying and interest in animal embryology and plant leaf and floral organ morphogenesis.

Butterfly-pollinated plants usually have pretty flashy flowers in hues like crimson and purple. these plants do not have the quantity of pollen that bee-attracting flowers do, however they've huge components of nectar to feed the butterflies.

Which variable is likely to undergo the largest change in value resulting from a mutation that introduces a new allele into a po
dsp73

Answer:

b. average heterozygosity

Explanation:

From the available options:

a. nucleotide variability

b. average heterozygosity

c. average number of loci

d. geographic variability

Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.

The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.

Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.

Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.

When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.

<em>The correct option is b.</em>
