People who are heterozygous for sickle cells disease are generally healthy because?
They are protected from malaria but don't have the actual disease, although they can still pass it on to their offspring
How can a lethal allele continue to be present in a gene pool even when they are selected against?
A harmful recessive allele remains in the population because both homozygous dominant and heterozygous genotypes produce the dominant, healthy phenotype. So the heterozygous genotype keeps the harmful recessive allele in the population.
Why are norwegians generally good looking?
We have blonde hair and blue eyes. We are thin because we have a healthy lifestyle.
Why did doctors use embryonic stem cells?
Scientists use stem cells because they can generate healthy cells and replace disease ones. Plus they allow them to test and better understand disease and test new drugs for effectiveness.
How a genetic disease can suddenly appear in a family with no previous history of the disease?
It could happen in two main mechanisms: 1) the allele responsible for the disease is recessive and so each of the parents are healthy portators of the allele (heterozygous), and all the sons which are homozygous for the allele (i.e. have two copies of the allele), with a frequency of 1:4, will be affected by disease, but not the others (heterozygouses and homozygouses for the good allele or wild type). 2) the mutation responsible for the disease (that acts in a dominant manner) is not present in any of the parents but happens only during the formations of gametes, and so will be transmitted to the son. There are also other mechanisms that are less frequent and more difficult to explain in a few words.

How is health and disease related to each other?
If you are healthy you are less likely to get diseases, and if you have diseases you are not healthy because you have a disease.
If you see healthy living yellow mouse can you tell if it is heterozygous or homozygous?
yes because of there specific traits that they have from the outside like their fur color, eye color and etc....
Explain how exercise can help prevent heart disease?
Exercise can help prevent heart disease because it works the heart muscle and keeps the body healthy. This has to be incorporated with healthy eating as well.
How can a lethal allele continue to be present in a gene pool even when they are selected against?
A harmful recessive allele remains in the population because both homozygous dominant and heterozygous genotypes produce the dominant, healthy phenotype. So the heterozygous genotype keeps the harmful recessive allele in the population.
What is the distinction between healthy and disease free?
healthy is a state of physical,social and mental well being while disease free is a state of absence of any body comfort. a healthy person can be disease free but a disease free person cannot be a healthy person

They are called Healthy.
