Answer 1

Answer:

Explanation:

1)The pairing of homologous chromosomes occurs during zygotene of prophase I of meiosis I.

2)An exchange of chromosome segments between non-sister homologous chromatids occurs and is called crossing over.

3)The points of attachment between non-sister chromatids of two homologous chromosomes are called chiasmata.

4)reduction division

5)DNA are two strands like structure of one chromosome which are attached at a point known as CENTROMERE.

Answer 2

Answer:

1. synapsis,take place during meosis
2. crossing over
3. chiasmata
4. reductional divosion
5. chromatids,centromere
