Meiosis has evolutionary significance because it results in
1. genetically similar daughters
2. four daughter cells
3. eggs and sperms
4. recombinations
A bivalent consists of
1. two chromatids and one centromere
2. two chromatids and two centromeres
3. four chromatids and two centromeres
4. four chromatids and four centromeres
Synapsis occurs between
1. a male and a female gamete
2. mRNA and ribosomes
3. spindle fibres and centromere
4. two homologous chromosomes
Bivalent chromosomes clearly appear as tetrads during:
1. Zygotene
2. Pachytene
3. Diplotene
4. Diakinesis
The beginning of diplotene is recognized by:
1. appearance of recombination nodules
2. crossing over
3. dissolution of synaptonemal complex
4. appearance of chiasmata
