Question

The following list of events happens during meiosis: Prophase I: Crossing over between homologous chromosomes occurs. Metaphase I: Tetrads line up at the metaphase plate. Anaphase I: Tetrads are separated. Telophase I: Nuclear envelopes reform around the separated chromosomes. Prophase II: Chromosomes condense. Metaphase II: Chromosomes line up at metaphase plate. Anaphase II: Sister chromatids separate into daughter chromosomes. Telophase II: Nuclear envelopes reform around the daughter chromosomes. Identify the answer choice that correctly lists the events from above that lead to new genetic combinations in the gametes.

Answer 1

The correct answer is "1 and 2". In meiosis, new genetic combinations are generated through the processes of prophase I (crossing over between homologous chromosomes) and metaphase I (tetrads lining up at the metaphase plate). These events result in the exchange of genetic material between homologous chromosomes, leading to genetic variation in the gametes.
