Answer: 1/16, or approximately 6.25% (see explanation below)
Explanation:
Answering this question requires two steps.
First, we need to figure out the probability that this couple will have a child with albinism in the first place. We know the following:
- Both parents are unaffected.
- The couple has already had one affected child.
- Albinism follows an autosomal recessive inheritance pattern.
Let ( M = normal gene ) and ( m = mutated gene ). Since the condition is recessive, the affected child can be assumed to have a “mm” genotype. Barring the possibility of a de novo mutation (which are assumed to be rare), the affected child must have inherited one ”m” allele from each parent. Since both of them are unaffected, however, we can assume that they are both carriers (genotype “Mm”). In conclusion, 1/4 of their offspring (25%) <em>for any given pregnancy</em> may be expected to have albinism. See the resulting Punnett square:
<u> | M | m </u>
<u>M | MM | Mm </u>
<u>m | Mm | mm </u>
Note that the question asks about the probability that not one but two consecutive births result in affected children. Since it can be assumed that both events are independent (meaning: the outcome of a pregnancy does not influence the outcome of following ones), we may apply the rule of multiplication for probabilities. The final answer is therefore 1/4 * 1/4 = 1/16.
Answer:
parathyroidoma
Explanation:
The condition where the parathyroid hormone is produces excessively is termed as Hyperparathyroidism. This condition arises when the balance between the calcium and phosphorus gets disturbed. The calcium and phosphorus balance is affected in following two cases –
a) When the parathyroid gland is not working properly due to its own problem usually termed as hyperparathyroidism or more specifically primary hyperparathyroidism
b) When the parathyroid gland is not working properly due to any other disease in the body affecting the functioning of parathyroid. It is termed as secondary hyperparathyroidism
Answer:
The change in time for the first quarter is 2.07 seconds.
The change in time for the second quarter is 1.09 seconds.
The change in time for the third quarter is 0.95 seconds.
The change in time for the fourth quarter is 0.81 seconds.
Explanation:
This is for table C
Although algae can photosynthesize, they lack other defining characteristics of plants such as true roots, stems and leaves, so they are not part of the plant kingdom.
