Look at the numbers used on the vertical axis. What would happen to the bars on the graph if these numbers
were changed to 100, 150, 200, and 300?

Answer and Explanation: You will find the graph in the attached file

When changing the numbers in the vertical axis of the original graph, you will see that bars tend to get shorter than they originally were. This occurs because new numbers are much bigger than the original numbers, the proportion of the bars changes because they must represent the same information in a much bigger space. Offenlly, this is a tool very used by media to mark a tendency when informing something. So It is very important whenever looking at any graph to see what the axes are telling you because by the size of the bars you might infer something that might be different from what is really going on.                                    

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
