Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.

<u>Answer:</u>
The sun’s spectrum though not a continuous spectrum allows us to represent the visible radiation. The spectrum from the sun has missing parts because the lights gets absorbed and not because of the sun.
Continuous spectra are discharged by any article that emanates heat. The light is spread out into a consistent band with each wavelength having some measure of radiation. For instance, when daylight is gone through a crystal, the light is spread out into it's colors.
When light passes through the sun’s atmosphere the spectrum is absorbed. The sun’s spectrum consists of seven colors VIBGYOR. When sun’s rays fall into the prism they are disbursed into seven colors.
