Initiation-transcription-translation e. None of the above is true 8. Which is correct if you crossbreed F2? a) b) c) d) e) I missed this class occurs via meiosis I and meiosisl 9. Chromosomal rearrangement a. True b. False c. They are both correct d. None is correct 10. The daughter cells from meiosis I and I cell divisions are 2 and 4 res a) True b) Fatse c) They are both correct d) None is correct

Explanation / Answer

5. Option b is correct. Dominant trait and recessive traits are expressed according to the presence of allele in gametes not due to chromosomal damage.

6. Option a is correct. Punnett square diagram shows the different combination of geneotypes and thus one will need a Punnett square to reveiew the ancestral tree.

7. Option c is correct. Replication, transcription and translation all these processes have three common steps. Initiation, elongation and termination.

8. Option d is correct. In F2 cross breed, the heterozygous (Tt) F1 plants are intercrossed. Which gives 1:2:1 (TT: Tt: tt) ratio.

9. Option b is correct. Chromosomal rearrangement occurs in meiosis I. In meosis II the chromatids are simply separated.

10. Option a is correct. Meiosis I is like mitosis which produces 2 daughter cell. These two daughter cells produce four daughter cells in meiosis II.
