Two pods of dolphins (same species) exist off the coast of Mexico. Pod A likes to swim and play at depth in cooler water. Pod B

likes to play on the crests of waves, preferring to stay a little closer to the light. Eventually the two pods preferentially choose mates which exhibit the same preference for swimming depth. Over time they lose the ability to interbreed. This speciation event is

Answer:

The correct answer is - speciation is sympatric.

Explanation:

Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.

This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.

Thus, the correct answer is - speciation is sympatric.

Describe each part of the geosphere including the parts that make up the lithosphere
snow_lady [41]

The geosphere is considered that portion of the Earth system that includes the Earth's interior, rocks and minerals, landforms and the processes that shape the Earth's surface. The geosphere may be taken as the collective name for the

  • hydrosphere (The hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers, and streams. The hydrosphere covers about 70% of the earth surface)
  • cryosphere (The cryosphere is the frozen water part of the Earth system. The Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water),
  • atmosphere( is a layer or a set of layers of gases surrounding a planet or other material body)
  • lithosphere is the substantial, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere below. The lithosphere is further subdivided into tectonic plates. The lithosphere is the most rigid of Earth’s layers.

In the the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At anot
Irina18 [472]

Answer:

15

Explanation:

According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.

Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.

Vestigial wings, red eyes = 80 : recombinant

Normal wings, purple eyes = 70 : recombinant

Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100

= [(80+70)/(420+80+70+430)]*100

= (150/1000)*100

= 0.15*100 = 15cM
