Answer 1

1. Endomitosis is the process by which chromonemata replicate but do not separate. Option (C) is correct.
2. Nucleolus is the site of rRNA transcription. Option (C) is correct.
3. Chromomeres are coiled filaments in which the genes are located, and they extend the entire length of the chromosome. Option (D) is correct.
4. Sporogenesis is the production of spores via meiosis in plants. Option (D) is correct.
5. Asci is a non-reproductive state. Option (A) is correct.
6. The spores of sordaria are found in the sacs known as asci. Option (A) is correct.
7. Polytene chromosomes are giant chromosomes in which DNA replicates but does not divide. Option (B) is correct.
8. Polytene chromsomes are formed in the process of endomitosis. Option (A) is correct.
9. Medium provides fruit flies with nutrients to ensure their survival and growth. Option (B) is correct.
10. The statement " polytene chromosomes are short chromosomes that replicate without separation'' is FALSE. Polytene chromosomes are considered as giant chromosomes because they grow bigger due to non-division after replication.
11. The statement "Drosophila are highly prolific which makes them model organism for genetic studies.'' is TRUE.
12. The statement "female Drosophila have round abdomen'' is FALSE. The females generally have pointed abdomen as compared to males.
13. The statement "majority of sordaria life cycle is haploid'' is TRUE.
14. Polytene chromosomes are fused at their center to form chromocenter. Option (A) is correct.
15. An ascomycete is a fungus whose spores develop within sacs. Option (A) is correct.
16. The statement "female Drosophila are smaller than male Drosophila'' is FALSE.
