What is homologous chromosomes?​
Yanka [14]

Explanation:

Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.

In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. So, our cells carry 46 total chromosomes, in two copies. However, each homologous chromosome can provide a different version of each gene. Two versions of each gene create more variety, lower the detrimental effects of negative mutations, and generally stabilize a population.

I hope it's helpful!!

In order to improve patient relations, a family practitioner should ____
Helen [10]
In the field of medicine we have a short adage that goes, "To cure sometimes, to treat often, to comfort always." Some say it was Hippocrates himself who said this. With that in mind, doctors should always have the patient's welfare in mind always. To improve relations with the patient, the doctor must do a lot of things to show respect. One of them includes simply sitting on a chair with an open stance and leaning slightly forward at an angle while the patient is talking to show that you are interested in what he or she has to say. Never hold the door knob while the patient is still talking as this is a sign that you want him to leave as soon as possible. Never look at far away things, like paintings on the wall or a clock, while the patient is talking because this is another sign of disinterest. And always allow the patient to express his or her self fully without interruption. There are more ways to improve patient relations but these are some good pointers to begin with.
