Answer: The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.
Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
The answer should be D.
Hope this helps!
