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%

B. 50%

Step-by-step 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:

Hence, the probability is 50%

square root

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
