Biology
1 answer:
lyudmila [28]3 years ago
3 0

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.

In a two-factor cross, genes that are close together on the same chromosome follow mendel's law of independent assortment.
torisob [31]

False, it violates Mendel's law of independent assortment.

About mendel's law of independent assortment:

According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.

During his research on the genetics of pea plants in 1865, Gregor Mendel made the first observation of an independent assortment of genes and their related phenotypes. Mendel was doing dihybrid crosses, which are unions of organisms with two different features. He found that the trait combinations in his hybrids' offspring did not always correspond to the trait combinations in the parental organisms.
