You can prove siblings are related by_
1. recombinant dna
2.hybridization
3.dna profiling
4.cloning

Well, there is only one realistic answer. Option One is when you take the DNA of two different people or creatures and combine them into one organism. Cloning wouldn't prove anything here, "hybridization" is weird - but it doesn't have anything to do with the situation. So only only remaining option is DNA Profiling - also known as DNA Mapping, which shows the DNA structure and order that can be seen the same way in siblings (slightly different of course but it is still the right answer).

Ithink the answer is a or d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Ithink b hope that
