I/GCSE Biology Question Analyses Topic: Biology - Short Questions
Exam Question:
1) State what are Mendelian disorders. Both thalassemia and colour blindness are categorised as Mendelian disorders. Justify.
2) Why does 'Swiss Cheese' develop large holes?
Answer:
For I/GCSE Biology, you should know:
1) Mendelian disorders: These conditions are caused by gene mutations. They are passed on to the next generation in accordance with Mendelian principles.
Both thalassemia and color blindness are autosomal recessive diseases and traits that can be passed down from one generation to the next.
2) When the lactic acid is consumed by the cheese-making bacteria, most especially P. shermani, it produces bubbles and releases carbon dioxide.
The bubbles don't just vanish; instead, they create tiny air pockets, which are what gives Swiss cheese its holes.
Work hard for your I/GCSE Biology examination!
End of analysis. Great!
