Answer:
<h3>
The event that doesn't happen during Meiosis I is B) Sister chromatids divide, resulting inhaploid cells. </h3>
Explanation:
During meiosis I,the sister chromatids are still attached at the centromere. In Anaphase I of meiosis I, the homologous chromosomes break their connections and separate out. The process of separation is called disjunction (dis-separate, junction-union). The separated chromosomes are called dyads (Gk. dyas-two) because each of them consists of two chromatids.
During anaphase II of meiosis II, the two chromatids of a chromosome separate completely forming the daughter chromosomes. At the end of anaphase II, four groups of chromosomes are produced, each group having haploid number.
Answer:
A gene is a basic physical and functional unit of heredity. Genes are present in the chromosomes of an organism. Genes carries the instructions to make molecules called as proteins which performs specialized function and building up the structure of living organisms. Genes are transferred from the parent organism to the offspring organism by the process of reproduction, hence maintains heredity in the living beings.
