Answer:
Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.
I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.
I tried to explain it as best as I could I hope it helps!
Answer:
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.

Among the listed options, we can conclude that option C which states that "<em>It results in the </em><em>diversity </em><em>of the </em><em>species</em><em> that enhances the probability of </em><em>survival</em><em>.</em>" is correct.
Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is <u>better adapted to a changing environment and promotes the faster </u><u>evolution </u><u>of a </u><u>species</u><u>.</u>
The main benefit of sexual reproduction is that it allows for a<u> </u><u>greater diversity </u><u>of the </u><u>species</u><u> which enhances the probability of </u><u>survival</u><u>.</u> This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (<em>the ability of a member of the species to choose a spouse with desirable traits</em>) <u>leads to </u><u>offspring </u><u>who over time are increasingly better </u><u>adapted </u><u>to life in the given </u><u>environment</u><u>, with specific traits tailored for </u><u>survival</u><u>.</u>
