Answer:
50%
Explanation:
This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb. 
According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb). 
Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb. 
Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%. 
 
        
             
        
        
        
Answer:
occurrence
Explanation:
Probability is a mathematical construction that determines the likelihood of occurrence or nonoccurrence of events that are subjected to chance factor. Thus the farmers are interested to know the probability of occurrence of rain before and after spraying. ... In this regard probability plays a great role

Explanation:
When cells asexually reproduce they split off from itself, and they have to replicate their DNA so both cells will have it because DNA is what tells the cell what to do, and how to work. The DNA will tell the cell parts all how to do their jobs, and will let the cell know when it should split off from itself. The DNA controls everything in the cell so without it the cell wouldn't know what to do.
