Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.
A. 7.5 feet
<u>Explanation:</u>
Wave base defines the depth of the water when it is in still condition.
Wave base is half of wavelength.
Wave base = wavelength/2
Given,
Wavelength = 15 feet
So, wave base = 15 feet/2 = 7.5 feet
When the wave height is divided by wavelength then it gives the steepness of the wave.
Therefore, the wave base is 7.5feet.
