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

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Zepler [3.9K]

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.

Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.

STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.
