Question

Destiny has distal symphalangism - her fingers and toes are stiff, with tiny nails. She looks it up and finds it is an autosomal dominant trait. Since her parents do not have it, she reasons that she has a new mutation. However, if she has children, each of them, assuming her partner does not have the condition, has a(n) ________ probability of inheriting the condition.

Answer 1

Answer:

1/2

Explanation:

Distal symphalangism is a very rare bone disorder characterized by ankylosis of the distal interphalangeal joints of the hands and/or feet.

Back to the prior issue,

Probability is a field of mathematics that deals with calculating

the likelihood of occurrence of a specific event.

The likelihood of an event is expressed as a number between zero

(the event will never occur) and one (the event is certain). For

example, the probability of an outcome of heads on the toss of a

fair coin is ½ or 0.5. The probability of an event can also be

expressed as a percentage (e.g., an outcome of heads on the toss

of a fair coin is 50% likely) or as odds (e.g., the odds of heads on

the toss of a fair coin is 1:1).

So the probability of her child inheriting her condition is 1/2 since there are only 2 possible outcomes.

Answer 2

Answer:

... has a 1/2  probability of inheriting the condition.

Explanation:

Distal symphalangism is a rare genetic disorder associated with the fusion of the distal interphalangeal joints of the hands and/or the feet that causes the rigidity of these joints
