Answer:
(E) bu cv+
Explanation:
Linkage is the phenomena in which two genes present on same chromosome have a tendency to get inherited together.
It is given that the two autosomal genes are linked and in repulsion. This means that the dominant allele of one gene is linked to the recessive allele of another gene and vice versa.
Hence, the parental type gametes will have bu cv+ and bu+ cv combination. Since in linkage parental gametes always appear in higher numbers than recombinant gametes, out of the given options bu cv+ set of genes will be present in most gametes produced by this cockroach.

Answer:
Are there any answer choices ?
Explanation:
Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.
A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.
The brightfield microscope is widely used in cellular biology and microbiological laboratories.
The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).
This maximum value can be reached by changing the objective lens.
