Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.
<h3>What are restriction enzymes?</h3>
They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.
The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

Answer:
Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
Both are heterozygous for the trait so we can expect that the cross would be:
Ss x Ss
S s
S SS Ss
s Ss ss
So the resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
So in summary:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair
ss 1/4 Long hair 1/4
