Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
Answer:
Incomplete dominance.
Explanation:
Mendel is known as the father of genetics. He had explained the different inheritance pattern present in different organisms. The Mendel explained the law of segregation, law of independent assortment and concept of dominance.
The incomplete dominance may be defined as the inheritance pattern in which the dominant trait is unable to express it self completely in the heterozygous condition and blending traits are produced. Here, the red color is unable to express itself in the heterozygous condition and produce pink color.
Thus, the correct answer is option (E).
Scientific inquiry requires logical ideas that can be tested
