Question

Anury is the absence or abbreviation of the tail in sheep (and also other animals). It is inherited in an dominant manner. A ram with anury is mated to a ewe with a normal tail. The ram’s father had anury, his mother did not. What is the probability that the ram and ewe will produce a lamb with anury?

A. 25%
B. 50%
C. 75%
D. 80%

Answer 1

B.50%

Explanation:

Answer 2

B. 50%

Explanation:

-The are two people involved in the breeding.

-The event of having an anury exists in only one of the two.

-Since probability is defined as the likelihood of an event occuring, this probability is calculated as:

`P(Anury)=(Anury\ Event)/(Total \ number \ of \ events)\\\\=(1)/(2)\\\\=50\%`

Hence, the probability is 50%
