Why does the law of independent assortment relates to crossing over and genetic linkage by?

This recombination of genes, called the crossing over of DNA, can cause alleles previously on the same chromosome to be separated and end up in different daughter cells. The farther the two alleles are apart, the greater the chance that a cross-over event may occur between them, and the greater the chance that the alleles are separated. - See more at: http://www.chacha.com/question/if-mendel's-law-of-independent-assortment-states-that-allele-pairs-separate-independently-of-each-other-during-meiosis.-how-does-this-law-relate-to-crossing-over-and-genetic-linkage#sthash.pJkZU4x9.dpuf

Explain how genetic engineering produces tomatoes that are ripe when they reach consumers?

Scientists have introduced a gene into the tomatoes that allow then to be picked green and transported great distances before they ripen completely.

What are the rungs of the DNA ladder made of?

The rungs of the ladder are pairs of 4 types of nitrogen bases (thymines, adenines, guanines, cytosines).

---

The pairs are guanine and cytosine (G-C), or adenine and thymine (A-T).
The rungs of the dna ladder are made of alternating sugars and phosophate groups.

What is the role of TE buffer in DNA isolation?

"TE" is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

What is the history of genetic engineering?

History of genetic engineering. Genetic recombination caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1972.

How would the human population be different if crossing over didn't happen during meiosis?

There wouldn't be any variety in the human population. Everyone would look more or less the same. This is because crossing over in meiosis allows the chromosomes to exchange genetic information to ensure that each daughter cell is unique and therefore, when reproducing, each person is also unique.
