Answer:
<em>A: Multiple genes contribute to human height</em>
Explanation:
What Mendel observed in pea plants is generally considered to be exceptions to what is obtainable in most living organisms. Instead of segregating and assorting independently, a lot phenotypic expressions are as a result of interaction of several genes on different loci (polygenic inheritance) while in some cases, multiple phenotypic expressions are controlled by a single gene.
Human height is a continuously varying character and has been studied to be controlled by multiple genes. In addition, the human height is often a result of complex interaction between genetics and the environment.
The correct answer is A.
I'm sure the answer is Viruses, but if your looking for something specific I don't think I can help you with that.
Answer:
In the given sequence of chromosomes to represents the centro-mere is ABCDEFG.H AEDCBFG.H.
In case of crossing over among B and C, made recombinants will be;
1) ABCDEA
2) H.GBCDEFG.H
However, out of these two made crossover chromosomes, only 1st recombinant chromosome as ABCDEA is the straight recombinants chromosome
