Genetic Inheritance and Disorders

What is the primary role of platelets in the human body?

• Fighting off infections

• Transporting oxygen to cells

• Helping blood to clot

• Digesting food particles

How is hemophilia classified in terms of genetic inheritance?

• As a dominant trait

• As a non-Mendelian trait

• As a sex-linked recessive trait

• As a sex-linked dominant trait

How many chromosomes are typically found in a human cell?

• 23

• 46

• 22

• 44

If a male has the genotype XhY, what does this mean for his health regarding hemophilia?

• He does not have hemophilia

• He is a carrier for hemophilia

• He has hemophilia

• He will develop hemophilia later in life

If a female is a carrier for hemophilia (X^H X^h) and a male does not have hemophilia (X^H Y), what is the probability that their child will have hemophilia?

• 25%

• 50%

• 75%

• 100%

In genetics, what are autosomes?

• Chromosomes that determine an individual's biological sex.

• Chromosomes that only carry recessive genetic traits.

• Any chromosome that is not a sex chromosome.

• Chromosomes found exclusively in male organisms.

Why are sex-linked recessive traits, like red-green color blindness, more commonly observed in males than in females?

• Males inherit two X chromosomes, increasing their chances.

• Females have only one X chromosome, making them less susceptible.

• Males have only one X chromosome, so a single recessive allele will express the trait.

• Females are always carriers of sex-linked recessive traits.

Which type of genetic disorder is typically too complex to be accurately predicted using a simple Punnett square?

• Disorders caused by a single dominant gene.

• Disorders caused by a single recessive gene.

• Disorders influenced by multiple genes and environmental factors.

• Disorders linked to sex chromosomes.
