BSEH SS Biology study plan

Build a one-page map linking meiosis, Mendelian ratios, and chromosomal theory so you can trace how allele segregation produces observed phenotypic ratios

Solve 20 monohybrid and dihybrid crosses from scratch, writing gamete combinations and expected ratios before checking answers

Distinguish incomplete dominance, codominance, multiple alleles, and polygenic inheritance using at least two worked examples each

Explain sex-linked inheritance and pedigree analysis well enough to predict outcomes for three given family histories

State the central dogma and describe transcription, translation, and the lac operon's regulatory logic without notes

Compare the major evidence for evolution: fossils, homologous and analogous structures, biogeography, and molecular phylogeny

Apply Hardy-Weinberg equations to calculate allele and genotype frequencies in a described population

Explain natural selection, genetic drift, founder effect, and bottleneck as distinct mechanisms with one example each

Trace gametogenesis in males and females, labeling ploidy and hormone control at each stage

Describe the human menstrual cycle as a hormone-driven timeline, naming the peaks and their feedback effects

Compare pollination and fertilization strategies in angiosperms, including double fertilization and embryo sac structure

Explain contraceptive methods and assisted reproductive technologies by their biological mechanism of action

Outline plant and animal reproductive strategies, distinguishing asexual, sexual, and vegetative propagation with examples

Define population growth models and calculate growth rates, carrying capacity effects, and life-table values

Describe ecosystem energy flow, trophic levels, and the ten percent rule with a worked numerical example

Explain nutrient cycling, especially carbon and nitrogen, and connect it to human impact

Classify biodiversity loss drivers and evaluate conservation approaches such as in-situ and ex-situ measures

Analyze pollution types by source, biological effect, and mitigation, including biomagnification calculations

Interpret environmental issues such as climate change, ozone depletion, and deforestation through their biological consequences

Apply ecological succession and species interaction concepts to unfamiliar case descriptions

Explain recombinant DNA technology step by step, including restriction enzymes, vectors, and selection of transformants

Describe PCR, gel electrophoresis, and DNA fingerprinting by principle, not just name

Evaluate biotechnological applications in agriculture, medicine, and industry along with their ethical and biosafety concerns

Summarize the biology behind major human welfare topics: vaccines, antibiotics, cancer, and drug resistance

Compare prokaryotic and eukaryotic cell structure and match organelles to their functions

Describe membrane transport, the cell cycle, and the phases of mitosis with their checkpoints

Explain photosynthesis and respiration as coupled pathways, tracing carbon and energy flow

Describe plant hormones and tropisms and predict plant responses to given stimuli

Trace human digestive, circulatory, respiratory, and excretory function and identify the regulatory hormone for each

Explain neural transmission and endocrine feedback using specific examples such as blood glucose control

Review human welfare topics from week 6 and connect them to physiological systems
