How does gene flow directly contribute to evolution? I'll mark brainliest

Biology

kifflom [539]2 years ago
7 0

Answer:

The correct answer is - B. It introduces new alleles into a population.

Explanation:

Gebe flow or migration is the transfer of the genetic material or transfer of genes from one population to another population of the same species. Gene flow is also responsible for the genetic change that leads to evolution.

Gene flow can contribute in various ways such as migration or vertical gene transfer parent to progeny, however, it can lead to evolution directly by introducing new alleles into a population.

Lisa [10]

Answer:

Transgenic

Explanation:

Recombinant DNA technology is used to make transgenic organisms. Genetic material from one specie is inserted into the genome of another thus modifying its characteristics. There are several ways of doing this including electroporation and transduction. This process is referred to as genetic engineering.

mamaluj [8]

Answer:

Option B and E and D

Explanation:

Technological advancement has led to growth of industries and manufacturing units and hence the net production of goods. This has led to the use of natural resources and release of pollution of all forms. Environmental research leads to intrusion into niche habitats and hence causes its destruction.

Option B, D and E are correct

Generally, it is not possible to determine whether nondisjunction failed to occur in oogenesis or spermatogenesis. However, it i
Maslowich

Answer:

XYY, spermatogenesis.

Explanation:

Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.

The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.  

Thus, the correct answer is XYY and  spermatogenesis

Which part of the iceberg displaces water equal in weight to the buoyant force?explain.
ohaa [14]

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:


Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi

So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.

Summary

<span>Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.<span>The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.</span></span>
