Answer:
1/4
Explanation:
The man is brown eyed so it can have both BB and Bb genotype but his mother was blue eyed and blue eyes is a recessive trait so his mother must have been bb. He would have got one "b" allele from her so his genotype must be Bb. Woman is also brown eyed with a blue type parent so her genotype must be Bb.
Bb X Bb :
B b
B BB Bb
b Bb bb
As evident, only 1/4 progeny will have recessive bb genotype which will result into blue eyes. So the probability that this couple will have a blue-eyed child is 1/4.
The procedure is called <span>Sigmoidoscopy</span>
The biotic factors are those that are living components that affect the population of the other organisms. From the given choices, the answer would be "A. rotting carcass". Although it is already dead, the fact that it is from a living organism makes it a biotic factor.
