Fill in the blank Most sex-linked Gene's are on the chromosome, simply because they are built of much more DNA. However, are more likely than to exhibit sex-linked traits.

most sex-linked genes are on the X chromosomes because they are larger than Y chromosomes. Males are more likely than females to exhibit sex-linked traits

Explanation:

Males are more likely than females to display recessive traits because a single recessive gene on the X chromosome is often not matched by a Y chromosome allele and therefore expressed.

X=2.5,  Y= 6.5

Step-by-step explanation:

It seems the triangle on the left is being transformed and a scale factor of 0.5 or 1/2 is being used since the 6 is half of 12. Therefore you divide 5 by 2 to get 2 and the 13 by 2 to get 6.5.
