A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the
Ratling [72]

Answer:

The sequence would be <u>ATTCATTCA</u>.

Explanation:

Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.

So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just <em>search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out.</em> Trust me, it's a great video, it's much better than my explanation.

The question is the following :
<span>What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.


The correct answer is A

In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.</span>
