Disruptive selection is a way of natural selection where extreme phenotype gets selected by the nature. Whenever there is sudden change in the environment, it creates sudden forces which favors the selection of extreme phenotype. In simple terms rather than having one ideal phenotype as observed in stabilized environment nature selects different types in the changing environment.

This is because disruptive environments favor disruptive natural selection that favors the extremes traits in a population. The variance of the trait increases and the population is divided into two distinct groups on both extremities. The attached picture will show how disruptive selection is modeled.

Each kernel of corn receives one allele from

each parent for the traits of color and texture.

Option B

<h3><u>Explanation:</u></h3>

Corn kernels are actually the seeds of corn. Corn kernels are formed because of the fertilization of both the Pollen and the ovule of the corn plants. This pollens and the ovules are formed by means of meiosis which takes different alleles of the same gene from both the parents and both the chromosomes of each parents. This is why during meiosis the events of crossing over and independent assortment leads to the variation of characters into the offspring. This is why the kernel colours of the the same ear of the corn remains same. This is how the corn plant receives the the kernel colours from both the parents and their colours remain constant for one particular ear. Also the gene of texture is achieved from both the parents by means of meiosis just like the corn colour. So there also independently assorted.
