FAQs on Sex Determination Video Lecture - Crash Course: Class 10
| 1. What is sex determination? |  |
Ans. Sex determination refers to the biological process of determining the sex of an individual, whether male or female. It is based on the combination of sex chromosomes inherited from the parents.
| 2. How is sex determined in humans? | |
Ans. In humans, sex is determined by the presence of sex chromosomes. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome determines the development of male characteristics.
| 3. Are there any other ways of sex determination in organisms? | |
Ans. Yes, there are other ways of sex determination in organisms. For example, in birds, reptiles, and some fish, sex is determined by the type of sex chromosomes. In some species of reptiles, the temperature at which the eggs are incubated can also determine the sex of the offspring.
| 4. Are there any exceptions to the typical XX and XY sex determination in humans? | |
Ans. Yes, there are exceptions to the typical XX and XY sex determination in humans. Some individuals may be born with variations in their sex chromosomes, such as XXY (Klinefelter syndrome) or XO (Turner syndrome). These variations can result in different physical and reproductive characteristics.
| 5. Can sex determination be influenced by environmental factors? | |
Ans. In some cases, environmental factors can influence sex determination. For example, in some species of reptiles, the temperature at which the eggs are incubated can determine the sex of the offspring. However, in humans and many other mammals, sex determination is primarily determined by genetics and not influenced by environmental factors.
