Punnett Squares and Sex-Linked Traits (UPDATED)
Amoeba Sisters・2 minutes read
Platelets are crucial for blood clotting, with hemophilia being a disorder that affects platelets, leading to continuous bleeding from minor injuries, as it is a sex-linked, recessive trait. Punnett squares are used to track X-linked traits like hemophilia by representing the recessive allele with a lowercase "h", aiding in predicting the likelihood of offspring inheriting specific traits.
Insights
- Platelets play a crucial role in blood clotting to prevent excessive bleeding, highlighting their essential function in maintaining health.
- Hemophilia, a sex-linked disorder carried on the X chromosome, results in continuous bleeding from minor injuries, emphasizing the genetic basis of this condition and the importance of understanding inheritance patterns through Punnett squares.

Recent questions
What are platelets used for?
Platelets are essential for blood clotting, preventing excessive bleeding. They help in the formation of clots to stop bleeding from wounds or injuries.
What is hemophilia?
Hemophilia is a disorder that affects platelets, leading to continuous bleeding even from minor injuries. It is a genetic condition that impairs the blood's ability to clot properly.
How is hemophilia inherited?
Hemophilia is a sex-linked, recessive trait carried on the X chromosome. This means that the gene responsible for hemophilia is located on the X chromosome, and the disorder is more common in males.
What is a karyotype?
A karyotype is a visual representation of an individual's chromosomes. In humans, a karyotype typically shows 46 chromosomes, with the sex chromosomes determining the gender of the individual.
How are Punnett squares used in genetics?
Punnett squares are used to track traits on sex chromosomes and predict the likelihood of offspring inheriting specific traits. In the case of hemophilia, the recessive allele for the disorder is represented by a lowercase "h" on the X chromosome in Punnett squares. This helps in understanding the inheritance pattern of X-linked traits like hemophilia.
