Answer:
 q = 0.42
Explanation:
This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;
p + q = 1
p² + 2pq + q²  = 1
where;
p =  the frequency of the dominant allele
q =  the frequency of the recessive allele
p² = the frequency of individuals with homozygous dominant genotype
2pq  = the frequency of individuals with heterozygous genotype
 q² = frequency of individuals with the homozygous recessive genotype
Since the total  population = 425
 q² = 
= 
 q² = 0.1765             
 To find q; we need to square root both side to           eliminate the square from  q².
∴  
 
 q = 0.4201 
 q = 0.42       (to two decimal places) 
 
        
             
        
        
        
Answer:
Ovary is an organ of the female reproductive system which is involved in the production and releasing of an ovum or egg. From the ovaries, the egg is released into the Fallopian tube in the uterus.
Ovulation can be described as the process in which an egg is released from the ovary. It may or may not be fertilized after being released. 
Similarities of the ovary and ovulation are that both refer to releasing of the egg.
