Answer:

Option (C)

Explanation:

The hydrothermal vents are the narrow cracks or passage at the ocean floor through which the hot water comes out. The water when percolates beneath the ocean floor through the cracks, then it gets heated up reacting with the hot molten magma and again comes out through those narrow openings. These narrow openings through which the liquid or a gas is allowed to pass is known as the hydrothermal vents.  

They are commonly found near the volcanoes and the mid oceanic ridge. It plays an important role in controlling the ocean water chemistry.

Hence, the correct answer is option (C).

In humans, blue eyes are caused by a recessive allele ("b") that dilutes pigment production. BB and Bb individuals have brown ey
saveliy_v [14]

Answer:

Probability that the son will be:

color-blind = 1/2

blue eyed = 1/8

blue eyed and color-blind = 1/16

Explanation:

Mother : BbXcX

Father : BbXY

Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.

XcX   X    XY :

     Xc    X

X  XcX  XX

Y   XcY  XY

Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.

Eye color is autosomal trait and blue color will be produced when the child has bb genotype.

Bb     X    Bb  :

   B    b

B  BB  Bb

b  Bb   bb

1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.

Probability of a son being blue eyed and color blind will be :

1/8 * 1/2 = 1/16
