FAQs on BBC Compacta Class 7 Solutions - Classroom Assignment- 71

1. What are the key differences between mitosis and meiosis?
Ans. Mitosis is the process of cell division that results in two identical daughter cells, while meiosis is the process that produces four genetically different daughter cells with half the number of chromosomes.
2. How does genetic variation occur during meiosis?
Ans. Genetic variation during meiosis occurs through the processes of crossing over, independent assortment, and random fertilization, which shuffle genetic material to create unique combinations of genes in offspring.
3. What is the significance of meiosis in sexual reproduction?
Ans. Meiosis is essential for sexual reproduction as it ensures genetic diversity in offspring by producing genetically different sex cells (sperm and egg) through the process of recombination and independent assortment.
4. How does meiosis contribute to the evolution of species?
Ans. Meiosis contributes to the evolution of species by generating genetic variation through the formation of unique combinations of genes in offspring, allowing for adaptation to changing environments and the survival of the fittest.
5. What are the stages of meiosis and their respective functions?
Ans. The stages of meiosis include prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, and telophase II. Each stage plays a crucial role in the reduction of chromosome number and the creation of genetically diverse sex cells.
