Study Notes
Defining Features of Sexual Reproduction
- Involves the combination of genetic material from two parents, creating genetic diversity in offspring.
- Produces gametes (sperm and egg) that fuse during fertilization to form a new organism.
Analogous Process in Bacteria
- Bacterial conjugation serves as an analogous process, where genetic material is exchanged between bacteria through direct contact, enhancing genetic variation.
Common Occurrence of Sexual Reproduction
- Most prevalent in multicellular organisms, particularly animals and plants, where it facilitates adaptation and evolution through genetic variation.
Diploid Precursor Cells and Haploid Cells in Eukaryotes
- Diploid precursor cells undergo meiosis, a specialized form of cell division that reduces chromosome number by half, resulting in the formation of haploid gametes.
- Meiosis includes two rounds of division: meiosis I and meiosis II, and involves processes such as crossing-over that increase genetic variation.
Outcome of Combining Two Gametes
- The fusion of two gametes during fertilization yields a diploid zygote, restoring the chromosome number and combining traits from both parents, which contributes to genetic diversity in the offspring.
