What is the remaining ratio of alleles? 2. Have any alleles been selected against?
Luden [163]

The remaining ratio of alleles is about 3:1

<h3>What about alleles?</h3>
  • The term "allele" is employed to refer to a gene's alternate form or variants.
  • For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
  • Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
  • For instance, a dominant allele can overcome the characteristics of other recessive alleles;
  • These features are what determine an individual's eye and hair color, for instance .
  • In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
  • Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
  • Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
  • Each gene during a human has two copies (or alleles), one from each parent.
  • Alleles significantly contribute to the event of each person's unique traits.
  • Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
  • An allele may be a gene's variable form.
  • Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
  • Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.

Rivers and streams are biodiverse ecosystems that are sensitive to change. please select the best answer from the choices provid
mylen [45]

It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.

<h3>What is river and stream?</h3>

A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.

On the other hand, a stream is a small river or a body of moving water confined by banks.

Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.

Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.

On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?
Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

  • abundance of food
  • high fertility rate
  • favorable environmental conditions
  • lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.
