Hemophilia is a sex-linked genetic disease is expressed by a recessive allele carried on the X chromosome. What is the best explanation on why this disease is more likely to be found in males than females?

• Males only inherit this disease if their Dad has it

• Males only have to inherit one X to have the disease

• Females cannot inherit this disease

• It is turned on by the hormones of male glands

A man and a woman have a daughter named Jennifer. Jennifer’s mother is color blind, the father is not. Years later, Jennifer is stopped by the police for driving through a red light. As the police officer is giving her a ticket, she states that she is not at fault because she is color blind.

Which of the following student explanations below best explains the truth?

• Jennifer is colorblind; she inherited it from her mom.

• Jennifer is colorblind; the genotype she expresses is XhXh.

• Jennifer cannot be colorblind because she did not inherit any recessive alleles.

• Jennifer cannot be colorblind because her father is not colorblind.

How many chromosomes are shown in a normal karyotype?

• 47

• 23

• 44

• 46
