Olin [163]

The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I

Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.  

When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.

MaRussiya [10]

Answer:

The benefits and harms of learning about my DNA are mostly in medical, personal, civil and criminal fields.

Explanation:

a) Pros: learning about my genome sequence could provide new information on the genetic basis of poorly understood diseases with the potential to provide new therapies, immediate benefits based on the current understanding of genetic and health. Being aware of elevated risks for known diseases could allow me to make proactive decisions about my health such as visiting the doctor frequently for more check ups, screening. Choosing one type of prescription drug over another based on my metabolism, changing my diet or exercise plan, informing reproductive decisions, moreover, I would personalize my health care precisely.
