Although genetic recombination ensures that only half the

the OA is correct.. it is D

A is wrong for the following reasons..

only is a key word here . When you read the part of the sentence below

Although genetic recombination ensures that ONLY half the genetic material, you immediately expect that the recombination happens for more than half

for example
although he had money to only buy ONE trouser, he managed to buy two on discount -- > (u expected him to buy only 1.. but he got more than one) this makes sense

Similarly
although he had money to only buy ONE trouser, he managed to come home empy handed -- > does not make sense because of the word ONLY


if i remove the word ONLY however,
although he had money to buy ONE trouser, he managed to come home empy handed - > this sentence makes sense

thats where B fits in...

substitute because in the example mentioned

Because he had money to only buy ONE trouser, he came home empty handed since he liked two and couldnt decide on which to drop

following the same lines..

because the combinations only happen at 50 %, it is possible that some genetic lines may die out

sorry if i made it a bit too long but hope this detailed explanation helps!!

Are you sure D is the OA here.

I like A. The tone and wording of the sentence points to a contrast.

Only 50% of genetic material is passed on.
But some genetic lines may die out entirely

Crick

The sentence says "ensures that only half the genetic material is passed", so "some genetic lines" should be part of the other 50% that won't be passed

I think the answer is D only, the statement goes like this,

Because genetic recombination ensures that only half the genetic material of a parent is represented in the offspring, some genetic lines (in the other half) may eventually die out entirely, even though there are numerous progeny(offspring or descendant)

Moreover, the last line indicates that, even though there are several combination for that 50% genetic material that is passed on, some genetic line may eventually die out

Even i thought the correct ans was A. But then, the OA listed was D.
Again, i read somewhere that a sentence beginning from 'Because' is considered incorrect.
Can any1 shed any light on the same??

Thanks

I choose D.

Although genetic recombination ensures that only half the genetic material of a parent is represented in the offspring, some genetic lines may eventually die out entirely, even though there are numerous progeny.
• Although:The diction is wrong in this sentence.
• Conclusively
• When
• Because: To better understand the usage of because here, place the main clause "some genetic lines may eventually die out entirely, even though there are numerous progeny because genetic recombination ensures that only half the genetic material of a parent is represented in the offspring.
• If (a conditional statement)

Can anyone please explain the usage of "if" clauses?

+1 for D

Hi krishnasty..

I 2 first thot that starting a sentence with Because is not allowed,
but later learnt that it is "OK" to start a sentence with 'Because' as long as the sentence is complete

We would mostly have a main clause after the subordinate clause (which has "because" in it) separated by a comma

For eg.,
Because it was raining. -- Incomplete and Wrong
Because it was raining, I stayed inside. -- Correct

Got tricked in this one.
Selected A

I selected A, but now i see why it's wrong , moreover, I should have seen the phrase .....''even though '' later on in the sentence and realized that it would just sound wrong to state something by saying '' Although blah blah blah, even though this happens.'' is there any rule about not having although and even though within the same sentence. looks and sounds bad.

Im sorry I still dont understand why A is wrong... I was stranded between A and D.
can someone explain why A is wrong?

regards

We need an although at the beginning of the sentence here I believe.

Although genetic combination ensures X, some genetic lines may still die out entirely.

Because genetic combination ensures X, some genetic lines may still die out entirely. It doesn't makes sense to me.

I'd go with A.

I originally went with A... but I did feel a bit uneasy about having "although and 'even though'" in the same sentence together. I agree that there must be some rule where those aren't in the same statement.

So I would agree that D is the answer... especially after repositioning it to the end of the sentence.

Great Q!

This sentence is tricky because you really have to read into the meaning. In other words, you have to understand the implication of each answer on the overall sentence.

Although genetic recombination ensures that only half the genetic material of a parent is represented in the offspring, some genetic lines may eventually die out entirely, even though there are numerous progeny.

A) Although
Although would imply an opposition to the next clause "some genetic lines may eventually die out entirely". However, does it make sense that "ensur(ing) half the genetic material represented in the offspring" is in contrast to "genetic lines dieing out"? No, genetic recombination ensuring material should cause it, or at least preserve it. If you do not follow this logic, the cue "even though" at the end of the sentence should place enough doubt in your mind although doesn't make much sense as an answer.

B) Conclusively
This would make the sentence grammatically incorrect. A better answer is "because"

C) When
Does genetic recombination occur only sometimes? This sentence doesn't say. "When" also implies that genetic recombination "ensures that only half genetic material..." sometimes occurs.

D) Because
This is our answer.

E) If
Doesn't make sense.

There cannot be two contrasts. Although and ... even though. So A is wrong. D is correct, giving a reason but contrasts the conclusions.

Although genetic recombination ensures that only half the genetic material of a parent is represented in the offspring, some genetic lines may eventually die out entirely, even though there are numerous progeny.
• Although
• Conclusively
• When
• Because
• If

Let’s look at the first part of the sentence which has two clauses (dependant and independent)-

Clause 1- Although genetic recombination ensures that only half the genetic material of a parent is represented in the offspring,

Clause 2- some genetic lines may eventually die out entirely

The use of “although” points towards a contrast that we are expected to see in the second clause.
But is there a contrast in the second clause?

No. Rather, the first part of the sentence tells us WHY some genetic lines may eventually die out. This is because genetic recombination ensures that only half the genetic material of a parent is represented in the offspring.

“If” is treated as a conditional on the GMAT.

Is it a condition for some genetic lines to eventually die out ? No.

The best choice is D.
