Dominant is always denoted by capital letters. Recessive is always denoted by lowercase letters. Homozygous refers to both alleles of the trait being the same. Heterozygous means both alleles of the trait are different.
Homozygous Dominant:
SS, BB
Heterozygous:
Ss, Bb
Homozygous Recessive:
ss, bb
Answer:
The system of nerves that govern reflexes, glands, the iris of the eye, and activities of interior organs that are not subject to voluntary control is called the <u>autonomic nervous system</u>
Explanation:
The autonomic nervous system is the involuntary division of the nervous system. It is composed of nerve cells that are related to the innervation and control of visceral organs, smooth muscle and secretory glands. It is divided into two systems, the sympathetic nervous system, which is responsible for activating most of the body's organs; and the parasympathetic nervous system, which is responsible for relaxing the activity of most organs, except those related to digestion.
The autonomic nervous system is responsible for regulating the involuntary visceral functions of the organism. Also, it's responsible for the maintenance of body homeostasis and the body's adaptation responses to variations in the external and internal environment. Thus, it helps to control, among other functions, blood pressure, heart rate, urinary emission, sweating, body temperature, among others. Most of the functions of the system are unconsciously regulated by means of visceral reflexes.
The right answer for the question that is being asked and shown above is that: "C. People can be tested for mutations on these genes." The statement that is true about BRCA1 and BRCA2 genes is that p<span>eople can be tested for mutations on these genes.</span>
The answer should be allele(s).
Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes.
However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing.
An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
