The pairing up of homologous chromosomes during meiosis is called? The group of 4 chromatids that forms during synapsis is called? The exchange of genetic material between arms of homologous chromosomes is called? The pairing up of maternal and paternal chromosomes (synapsis) during meiosis happens in? During meiosis, crossing over happens in? During meiosis, independent assortment happens in?
Understand the Problem
The question is asking about various concepts related to meiosis and the processes involved, specifically focusing on synapsis, chromatid groups, genetic material exchange, and stages of meiosis. The user seems to be looking for answers to multiple-choice questions based on these concepts.
Answer
3. Synapsis, 4. Tetrad, 5. Crossing over, 6. Prophase I, 7. Prophase I, 8. Metaphase I
The pairing up of homologous chromosomes during meiosis is called synapsis. The group of 4 chromatids that forms during synapsis is called a tetrad. The exchange of genetic material is called crossing over. Synapsis and crossing over occur in prophase I, while independent assortment happens in metaphase I.
Answer for screen readers
The pairing up of homologous chromosomes during meiosis is called synapsis. The group of 4 chromatids that forms during synapsis is called a tetrad. The exchange of genetic material is called crossing over. Synapsis and crossing over occur in prophase I, while independent assortment happens in metaphase I.
More Information
During meiosis, homologous chromosomes pair and exchange genetic material, increasing genetic diversity in offspring.
Tips
A common mistake is confusing the stages of meiosis where these processes occur. Remember, synapsis and crossing over occur in prophase I, while independent assortment occurs in metaphase I.
