This week in Biology we only had 2 sessions, on the 27th and on the 30th. On Monday, we had a quiz about monohybrid and dyhibrid tables, as well as pedigrees. I was able to answer the monohybrid and dyhibrid questions correctly, and solve the murder case about dominant and recessive traits. At first I wasn’t sure about the pedigree question, but in the end I was able to answer them correctly.
On Thursday, we had a mini lesson about sex-linked genes diseases. I learned that sex linked diseases are diseases that are inherited by the sex genes, which are the X and Y chromosomes. Common sex linked diseases are the X-linked traits, and are usually inherited to sons from their mothers. While Y-linked traits are inherited to sons from their parents, but these diseases are rare because they are recessive. X-linked diseases are more common because the X chromosome are the dominant ones, and it shows especially in male because the Y chromosome is smaller. Some X-linked diseases are hemophilia, red-green color blindness, and muscular dystrophy (MD), and an example of a Y-linked disease is hypertrichosis pinnae.
