Homologous chromosomes or homologous are a set of chromosomes one coming from the mother and the other comes from the father, they have same genes in same loci so as to enable pairing during meiosis.
1. A sister chromatid refers to the identical copies formed by replication of a chromosomes which are joined together by a common centromere.
2. A) meiosis II b) telophase I of meiosis
These two are similar to mitosis.
3. A) both b) both c) mitosis d) both
E) meiosis f) both g) meiosis h) meiosis I) mitosis
4. The exchange of genes between homologous chromosomes that results in the parental characteristics in the offsprings.
Crossing over occurs between prophase 1and metaphase 1.
5) mitosis the parent cell starts with haploid cells and ends with haploid cells
6. In meiosis the parent cell starts with diploid cell and ends with four haploid cells.
7. Sex cells have 23 chromosomes i.e. n when compared to the parent cells whihave 46 chromosomes i.e. 2n.
