The best way to know the probabilities here is to do each cross and see the results.

a. Aa Bb Cc Ddx aa bb cc dd

Aa Bb Cc Dd

Aa Bb Cc Dd

aa bb cc dd

aa bb cc dd

You have 50% chances of Aa Bb Cc Dd which is phenotypically the same as one of the parents, and 50% chances of aa bb cc dd which are phenotypically the same as one of the parents.

b. aa bb cc dd x AA BB CC DD

aA bB cC dD

aA bB cC dD

aA bB cC dD

aA bB cC dD

You have 100% chances of having aA bB cC dD offspring, and it will be phenotypically the same as the AA BB CC DD because of the dominant allele.

c. Aa Bb cc Ddx Aa Bb cc Dd

AA BB cc DD

Aa Bb cc Dd

aA bB cc dD

aa  bb cc dd

You have 25% chances of AA BB cc DD, 50% chances of Aa Bb cc Dd which are phenotypically the same as both the parents and 25% chances of aa bb cc dd.

d. aa bb cc dd x aa bb cc dd

aa  bb cc dd

aa  bb cc dd

aa  bb cc dd

aa  bb cc dd

You have 100% chances of having aa  bb cc dd which are phenotypically the same as both the parents.

MAIN IDEA: Glycolysis is needed for cellular respiration.
FrozenT [24]

Answer:

Glycolysis is an organic catabolic process where small molecules are originated by splitting of a larger molecule.

Explanation:

A Catabolic reaction is a way by which we obtain any break down of a big organic matter into small parts.

Glycolysis is a great example of any catabolic reaction. Let see this process by the equation-

C6H12O6 (glucose) + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH3(C=O) COOH + 2 ATP (energy) + 2 NADH + 2 H+

From the upper equation, we can see that it fracture the Glucose (energy carrier) and generates pyruvic acid (energy supplier) and ATP (energy) with some other byproducts, so we can easily say the primary function of Glycolysis is to produce energy by splitting one energy-carrying molecule.
