Colorblindness is a sex-linked recessive disorder. If the daughter of a couple is colorblind, what are the two possible genotypes of her mother?
Males are more likely to suffer from a sex-linked disease or disorder because
A. males are the weaker sex
B. males have less DNA
C. males have 1 X chromosome, so the disorder is more likely to be expressed
If a trait shows up more commonly in men than women it is probably
A. not inherited
B. on the x chromosome and dominant
C. on the x chromosome and recessive
D. on a normal body chromosome
Mendel’s Law of Segregation means?
A. Every person has two alleles for each trait, they segregate from each other and the dominant is passed more often.
B. Every person has two alleles for each trait, Where two traits are being passed, they do not effect each other.
C. Every person has two alleles for each trait, they segregate from each other and are passed down at random.
D. Every person has two alleles for each trait, they segregate from each other and the recessive is passed more often.

A. homozygous
B. asexual
C. homologous
D. genes
The sex of a child is determined by
A. whether the father’s sperm contains an x or y chromosome
B. whether the mother’s egg contains an x or y chromosome
C. the age of the parents
What is it called when a sperm and egg meet?
A. meiosis
