Web2 uur geleden · During meiosis, cells combine one round of DNA replication with two rounds of chromosome segregation, all of which is tightly regulated to ensure that gametes inherit the correct number of chromosomes. Errors in meiosis can lead to aneuploid gametes that cause infertility, birth defects and miscarriages [ 1 ]. WebI use meiosis to transition from teaching about DNA replication and protein synthesis to then teaching about inheritance patterns, pedigrees, mutations, and genetic disorders in my Heredity unit. It really helps students to see how ALL of these inheritance topics work together! 3. Emphasize the complexity of inheritance.
