BLANK 1 ANSWERS

1 mice undergo the same gene mutations

2 mice share a common ancestor with humans

3 mice and humans have different ancestors
BLANK 2 ANSWERS
1 homologous
2vestigial
3analogous

Answer 1

The DNA of humans and mice is almost 92% similar. This similarity indicates that mice undergo the same gene mutations Mice have a tail, while humans have a tailbone. The tailbone is a vestigial structure in humans.

Answer 2

Answer:  

1. mice share a common ancestor with humans, 2 vestigial

The 92% similarity in the DNA of human and mice indicates that these two exhibit common ancestry which means they are evolved from a sample ancestor and exhibit similarity at the genetic level. The vestigial organs are those organs which are common in many organisms but does not perform a specialized function in the body of organism. The human tail bone is the example of vestigial organ is common in primates and related animals. In humans their is no function of the tail bone but in animals it connects and supports the tail.
