Skeletal muscles play a key role in the movement of blood around the body. Veins embedded within a muscle are compressed during contraction of that muscle, causing an increase in blood pressure due to the presence of one-way valves within the veins.
The answer is;
- The recombination frequency is proportional to the distance between the two genes
- The lower the recombination frequency, the farther apart two genes are on the chromosome
Genes that are close together are more likely to be passed together to offspring during recombination. Geneticist compares the ration between the proposed phenotype offspring and actual phenotype offerings in a population. The higher the recombination frequency (centimorgans," or cM), the closer the genes are linked together, physically.
