Which of these choices describes the purpose of a Punnett square? O to diagram family relationships that include several generat
ions to compare inherited traits to acquired traits o to illustrate how the alleles of parents might be passed on to their offspring O to explain why some genes are recessive and others are dominant
Answer: to illustrate how the alleles of parents might be passed on to their offspring
Explanation: This is a punnet square. Let's say your mum has brown eyes and your father has brown eyes too. Why? Their alleles (different forms of the same gene) contain the genetic information Bb and Bb. B stands from brown dominant meaning that would be your father's and mother's eye colour. However, the lowercase b represents blue eyes. They have an allele for getting blue eyes but they don't express it because it is always recessive. When the egg in a woman's womb is fertilised, it connects with the sperm cell and makes genetic information and DNA. The punnet square shows the different combinations of alleles the new baby would have. BB = brown Bb= still brown bb= blue
Explanation: The space in the center of the eyeball is filled with a clear jelly-like material called the vitreous humor. This material allows light to pass through to the retina. It also helps the eye keep its round shape.
