Question

match each step of meiosis with what happens during that step. (2 points) meiosis i crossing - over meiosis ii end of meiosis sister chromatids split apart, like normal cell division. matching chromosome pairs split into two new cells four different haploid gametes are made. genetic material is traded between matching chromosomes to make new gene combinations

Explanation:

• Meiosis I: In Meiosis I, homologous (matching) chromosome pairs separate. This is the first division in meiosis where the chromosome number is halved from diploid to haploid in the resulting cells.
• Crossing - Over: Crossing - over occurs during prophase I of Meiosis I. It is the process where genetic material (segments of chromatids) is exchanged between homologous chromosomes. This leads to new gene combinations.
• Meiosis II: Meiosis II is similar to mitosis. Sister chromatids, which are the replicated copies of a single chromosome, separate.
• End of Meiosis: At the end of meiosis (after Meiosis I and Meiosis II), four non - identical haploid gametes are produced. These gametes have half the number of chromosomes as the original parent cell and are genetically diverse due to crossing - over and independent assortment (in Meiosis I).

Answer:

• Meiosis I: Matching chromosome pairs split into two new cells.
• Crossing - Over: Genetic material is traded between matching chromosomes to make new gene combinations.
• Meiosis II: Sister chromatids split apart, like normal cell division.
• End of Meiosis: Four different haploid gametes are made.
