The statement " Each gene in the human genome codes for a single protein. "is just wrong, as according to the basic knowledge of human genome, o<span>nly about 2 percent of the genome codes for proteins. This answer does make difference and clearly explaines why the previous one is wrong. Hope you will find it helpful!</span>
Answer:
The correct answer is- 4:0
Explanation:
Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.
Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.
S s
S SS Ss
S SS Ss
Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.
They use them as food and habitats.
Answer;
-DNA
Explanation;
-DNA stands for deoxyribonucleic acid. It's the genetic code that determines all the characteristics of a living thing.
-It contains the genetic instructions for the development and function of living things. These instructions are needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the activities in our bodies.
