Question

can we link the pronouns of two clauses when used with ',and'.

eg

the  boy  did blah blah blah , and one of  his  most important achievement is blah blah blah.

can we use his as pronoun for the boy when both the clauses are joined by ",and"?

what if the pronoun in the clause after ',and' is not the subject, but the object of the clause?

can we use then?

eg: I know this question has been discussed but I m using it as an example for my doubt

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

(a)that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved 
(b) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving 
(c)suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving 
(d) to suggest that the elephant had descended from an aquatic animal and its trunk originally evolving 
(e) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

what if the 'e' were something else.
eg

(e) to suggest that the elephant is descended from an aquatic animal and  that  its trunk originally evolved

can we say e is still correct?

Doubt 2:

If the answer choice A is grammatically incorrect, do we have to keep the meaning for the other choices.

eg. A) X may increase Y - grammatically wrong

B) X increases Y - grammatically correct.

can we mark the B as correct choice?

My view on 1st doubt:

'and' without comma before it assumes same subject from earlier half. So if you remove 'that', 'its' becomes confusing.

Per my opinion, your example was also correct. In the question, it has to be parallel structure.

The pronoun issue you're mentioning really comes down to an issue of logic. If there is only ONE logical antecedent for a pronoun in a sentence, then it is grammatically correct to use a pronoun in an independent clause following a comma+and.

The boy went to the park, and he played fetch with his dog.

The only logical antecedent for "he" and "his" here is "boy," so this would be correct. But look at this sentence:

The boy went to the park with his father, and he bought an ice cream.

Now, it's unclear whether "he" refers to the boy or his father, so this sentence wouldn't work on the GMAT.

The question you use as an example here is actually a little bit different. It's testing your ability to see parallelism in the "that" clauses: embryologists have found evidence that suggests THAT x and THAT y. On the GMAT, when you see this structure (discovered THAT x and THAT y, realized THAT x and THAT y, etc.) you MUST use the word "that" in front of both clauses in order to maintain parallelism.

Regarding your second question, meaning is very important insofar as the correct answer choice must be logical. However, the most logical meaning might be different from the meaning expressed in the sentence as written (answer choice A). It's fair game for the GMAT to change whatever they want in the underlined portion -- your job is to determine if the choice is both grammatically correct and logical on its own.

Hope that helps!
