A chromosome is made of two sister chromatids that are joined by a centromere.
<span>Compound Microscope
Compound microscope is commonly used in the schools and colleges.
It comes under the category of microscopes used in biology.
It has two lenses namely the objective lens and the ocular lens.
It provides a magnification of 1500X.
Eyepiece lens is of 10X or 15X power.
It is used to observe bacterial, protozoa, various cells, etc.
</span><span>Dissecting Microscope
It is also called stereo microscope.
Its magnification power is less than the other microscope.
It gives a 3 dimensional picture.
Due to the low magnifying power they are used to observe little bigger objects than other microscopes.
They are used in the surgeries, dissection, forensic science etc.</span>
It’s true. have a great day/night!
The correct answer is option C
The frequency of the homozygous recessive genotype
In the Hardy-Weinberg equation, p is the frequency of the dominant allele, and q is the frequency of recessive allele then the frequency of genotype is represented by
p^2 = p x p = frequency of the homozygous dominant genotype ( AA)
q^2 = q x q = frequency of the homozygous dominant genotype (aa)
2 pq = p x q = The frequency of the heterozygous dominant genotype ( Aa)
