A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylt

hiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous

Answer:

The correct answer is -

A) BbTt x bbTt

B) .5^4 or 1/16 or 0.0625

Explanation:

As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.

For Branchydactylus and For tasting :  man and women will be heterogeneous.

Hence,

The Genotype of man = BbTt

The Genotype of wife = bbTt

b. Answer = 0.0625

For Branchydactylus:

Bb X bb

Possible genotypes:

B b

b Bb( Brachydactylus) bb(normal)

b Bb (Brachydactylus) bb (normal)

The probability of a single child being Branchydactylus = 2/4 = 0.5

So,  Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy
Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein  3D structure  for binding with substrates during   reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites  occupied, therefore denying the inhibitor methylalchol  chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites

The process of photosynthesis can be represented by the chemical formula A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy B) C6H12O6 + 6H
miv72 [106K]
C.
6CO2 + 6H2O + Light -> C6H12O6 + 6O2

Light is needed as energy in order for photosynthesis to occur. Photosynthesis converts carbon dioxide and water into oxygen and glucose.
