Anaphase-I chromosomes having distinct c...

Anaphase-I chromosomes having distinct chromatids are called dyad.

Text Solution

**Step-by-Step Solution:** 1. **Understanding Anaphase I**: Anaphase I is a stage in meiosis where homologous chromosomes are separated and pulled towards opposite poles of the cell. This is a critical phase in the reduction of chromosome number. 2. **Chromosome Structure**: Each chromosome consists of two sister chromatids joined at a region called the centromere. In the context of Anaphase I, we are dealing with homologous chromosomes, which are pairs of chromosomes (one from each parent) that are similar but not identical. 3. **Definition of Dyad**: A dyad refers to a pair of homologous chromosomes that are still connected by their centromeres but have separated into distinct chromatids. In Anaphase I, each homologous chromosome is made up of two sister chromatids, thus forming dyads. ...
