How do you calculate the total magnification?
What will be an ideal response?
Ans: To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

In Lake Malawi cichlid fishes, one can observe two color variants, Black Barred (BB) and Orange Blotch (OB)
Sex in these fishes are not determined by a sex chromosome, but rather by a gene on an autosome which produces either males or females. Both of these phenotypes are controlled by one biallelic locus each. OB females have a selective advantage in terms of their survivability: The OB phenotype allows females to blend into their background. OB males have a selective disadvantage because their reproductive coloration is dis-rupted and they have little mating success. How would this process influence the as-sociation of alleles at the color locus and sex determining locus? What will be an ideal response?
