Answer: A. Trait L is governed by a dominant allele.
Options:
A. Trait L is governed by a dominant allele.
B) Trait L is governed by a recessive allele.
C) Trait L involves polygenic inheritance.
D) None of these would help to clear up the confusion.
Explanation: A dominant allele gives humans a dominant trait that is passed on from their parents. This physical trait, or characteristic will always be present whether it is combined with the same characteristic or a different one in their genotype. For example, dark hair is dominant over blonde hair. This makes blonde hair a recessive trait, so when an allele controlling dark hair is present, the person will have dark hair regardless of whether one of their parents has passed on the recessive allele that gives blonde hair.
In the question above, explaining to the woman that trait L is governed by a dominant allele will help her understand that it must have been passed on to her from one of her parents.

Explanation:
isovolumetric contraction is an event occurring in early systole during which the ventricles contract with no corresponding volume change (isovolumetrically). This short-lasting portion of the cardiac cycle takes place while all heart valves are closed.

<h3>
What should be done if a youngster is not responding?</h3>
- If a baby or child is unresponsive and has abnormal breathing (e.g., taking irregular or noisy breaths, or has stopped breathing entirely) and no signs of life, they are in cardiac arrest.
- When a baby or child goes into cardiac arrest, their heart stops beating and they are unable to pump blood throughout their body.
- This means that vital organs, such as the brain, are deprived of oxygen and can begin to deteriorate within minutes.
- Although cardiac arrest occurs less frequently in babies and children than in adults, it is still fatal.

Explanation:
Answer:
C. This is a case where hybrid offspring of the two species are less fit than either of the parent species. In the geographic areas where the populations overlap, natural selection has reinforced color differences that serve as reproductive barriers between the two species.
Explanation:
Nature has developed certain reproductive barriers or mechanisms of reproductive isolation. These occur to prevent members of different species from mating and producing offspring or to make sure that the offspring are sterile.
