If the dominant allele is t and the recessive allele ("non-taster") is n, than tn and tt are the genotypes of a "taster". tn is heterozygous and tt is dominant homozygous. nn is the genotype of a "non-taster" and it is recessive homozygous.
Answer:
Lisa and Monica
Explanation:
<em>The correct answer would be Lisa and Monica.</em>
<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>
In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.
Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).
The pituitary gland is often called the "main gland" of the body, as it regulates many of the activities of the endocrine glands. ... HET (thyroid stimulating hormone) stimulates the thyroid gland to release T3 and T4 to stimulate metabolism in other cells of the body.
Answer:
According to the science magazine Scientific American, the sunset is reddish because, when the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only colour light that is not scattered away is the long wavelength light, the red.
Answer:
Airways diameter can influence the airflow resistance.
Explanation:
Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow.
Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.
