What are the risks of gene mutation?

Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.

How do you calculate risk in biology?

Relative risk is the comparison of one group developing a particular disease to another group. The primary group of interest is compared to an 'unexposed' group, then relative risk is calculated by dividing the incidence rate in the primary group by the incidence rate in the comparison group.

What is the probability of having a son that is normal?

In normal meiosis, one primary spermatocyte ultimately becomes four sperm cells: X, X, Y, and Y. Therefore, if meiosis is normal and no other factors are involved, there should be a 50% chance of conceiving a boy or girl.

What is the genotype of RR?

The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.

What genetic factors mean?

In many diseases genetic factors are important. This means that part, or all of the risk, is passed down from one's parents. Certain diseases are caused by an abnormality in one single gene and CADASIL is one of these diseases. Genes produce proteins which are necessary for normal functioning of the body.
