Let’s break this down! I’ll give you a study guide covering asexual reproduction, sexual reproduction (in humans and plants), and Mendelian genetics — then I’ll create a test for you. ⸻ Study Guide for Asexual Reproduction, Sexual Reproduction, and Mendelian Genetics ⸻ I. Asexual Reproduction • Definition: Involves a single parent, producing offspring genetically identical to the parent (clones). • Types of Asexual Reproduction: • Binary Fission: Simple cell division (e.g., bacteria). • Budding: New organism grows from a bud on the parent (e.g., yeast, hydra). • Fragmentation/Regeneration: Organism splits, and each part grows into a new organism (e.g., starfish). • Vegetative Propagation: New plants grow from parts of the parent plant (e.g., runners in strawberries). • Parthenogenesis: Offspring develop from unfertilized eggs (e.g., some lizards, insects). • Pros and Cons: • Pros: Fast, no need for a mate, energy-efficient. • Cons: No genetic variation, susceptible to environmental changes. ⸻ II. Sexual Reproduction (Humans & Plants) Humans: • Process: • Gametes (sperm and egg) produced by meiosis. • Fertilization forms a zygote (diploid cell). • Male Reproductive System: Testes, epididymis, vas deferens, prostate, urethra, penis. • Female Reproductive System: Ovaries, fallopian tubes, uterus, cervix, vagina. • Hormonal Regulation: • Male: Testosterone (sperm production, secondary characteristics). • Female: Estrogen & progesterone (menstrual cycle, pregnancy). Plants: • Process: Alternation of generations (sporophyte & gametophyte stages). • Pollination: Transfer of pollen to stigma. • Fertilization: Sperm (from pollen) fuses with egg in ovule. • Structures: Stamen (male), carpel/pistil (female). • Seed & Fruit Development: Fertilized ovules become seeds; ovary becomes fruit. ⸻ III. Mendelian Genetics • Gregor Mendel’s Experiments: Pea plants, discovered inheritance patterns. • Key Concepts: • Genes & Alleles: Genes determine traits, alleles are gene variants. • Dominant vs. Recessive Alleles: Dominant alleles mask recessive ones. • Homozygous vs. Heterozygous: Same alleles (AA or aa) vs. different alleles (Aa). • Laws of Inheritance: • Law of Segregation: Allele pairs separate during gamete formation. • Law of Independent Assortment: Genes for different traits sort independently. • Genetic Crosses: Punnett squares, monohybrid/dihybrid crosses. • Probability & Ratios: Phenotypic/genotypic ratios. • Non-Mendelian Inheritance: Incomplete dominance, codominance, multiple alleles, polygenic traits, sex-linked traits. ⸻ AP Biology Practice Test Total Questions: 30 (Multiple Choice) Section 1: Asexual Reproduction (6 questions) 1.
