Human Genetics

The diagram below represents the karyotype of a person with a genetic disorder.

Which is the likely cause of this condition? (3.2.2)

• nondisjunction during mitosis

• nondisjunction during meiosis

• chromosomal deletion during mitosis

• chromosomal deletion during meiosis

A human egg cell might contain (3.2.1)

• 22 autosomes and an X chromosome

• 22 autosomes and a Y chromosome

• 45 autosomes and an X chromosome

• 45 autosomes and a Y chromosome

Human males are much more likely to have hemophilia than human females. This is the case because: (3.2.2)

• the gene for hemophilia is carried on the Y chromosome

• hemophilia is carried on autosomes

• the gene for hemophilia is sex-linked

• hemophilia is a contagious disease to which males are more susceptible

What type of inheritance is shown in the pedigree below? (3.2.2)

• autosomal dominance

• codominance

• incomplete dominance

• sex-linked recessive

The type of inheritance pattern demonstrated here is

• x-linked recessive

• autosomal dominant

• x-linked dominant

• co-dominant
