Total magnification of objects is 12x.

Dissecting microscopes are microscopes with only one set of lenses so they have less magnification than a compound microscope.

The eyepiece, or ocular lens of microscope, usually has a magnification of 10x. The numbers on magnification knob range from about 0.7 to 3. So, when you want to calculate the total magnification multiply the magnification on the eyepiece with the number on the magnification knob.

What conditions are necessary for populations to remain in hardy-weinberg equilibrium
elena-14-01-66 [18.8K]

Answer:

Large population

Random mating

No evolutionary mechanisms (mutations, genetic flow,, genetic drift, natural selection)

Explanation:

According to  Hardy-Weinberg model, allele frequence (or genotype frequencies) will remain constant through generations in the absence of disturbing factors, evolutionary mechanisms. Such constant population is in Hardy-Weinberg equilibrium (no evolving population). Factor that can disturb equilibrium of the population are nonrandom mating, mutations, gene flow, natural selection, genetic drift.

According to Hardy-Weinberg model:

p2+2pq+q2=1 (p+q=1)

p2 is the frequency of dominant homozygous genotype

2pq is is the frequency of heterozygous genotype

q2 is is the frequency of recessive homozygous genotype
