BIO220H1 Lecture Notes - Lecture 1: Inbreeding Depression, Litmus, Autosome
Genetic data of behavior and ecology patterns in data. In of population (mt, y) (autosomes, x) (mt, autosomes, x) (y) 2) no, weak inbreeding depression
393
BIO220H1 Lecture Notes - Lecture 2: Lactase Persistence, Lactose Intolerance, Lactase
Selection on one species impose selection on another species. E. g. wolves select on moose, moose becomes stronger which selects on wolves, wolves them
387
BIO220H1 Lecture Notes - Lecture 3: Crop Diversity, Selective Breeding, Zygosity
361
BIO220H1 Lecture Notes - Lecture 4: Extinction Vortex, Genetic Drift, Nucleotide Diversity
Small population greater genetic drift loss genetic variety gene frequency decrease. Inbreeding arises homozygosity increases inbreeding depression low

BIO220H1 Lecture Notes - Lecture 5: Exponential Growth, Overfishing, Escapement
347
BIO220H1 Lecture Notes - Lecture 6: Atlantic Cod, Directional Selection, Phenotype
Threshold in size: e. g. size of fish determines whether they can escape the nets or not. Trophy ornaments: e. g. size of antler racks or horns in shee

BIO220H1 Lecture Notes - Lecture 7: Sigmoid Function, Exponential Growth, Population Model
545
BIO220H1 Lecture Notes - Lecture 8: John Bennet Lawes, Working Animal, Rothamsted Research
Bio220 lecture 8: ecology of ancient and modern food production. Quaternary period: dramatic changes of era, glacial periods and interglacial periods.
359
BIO220H1 Lecture Notes - Lecture 9: Phosphorus Cycle, Water Cycle, United States Department Of Energy National Laboratories
In the cold war, us and ussr"s use of nuclear weapon were inevitable. Downside: radionuclide/excess nuclear energy pieces would enter food chains and h
551
BIO220H1 Lecture Notes - Lecture 10: Svante Arrhenius, Primitive Equations, Chlorofluorocarbon
Bio220 lecture 10: greenhouse gases and climate change. Earth experienced many climate changes, including ice age that alternates between glacial and i
450
BIO220H1 Lecture Notes - Lecture 11: Cherry Blossom, Phenology, Koch Family
*many organisms use temperature to regulate their life cycles, such as the reproduction time. We can use data on timing of organisms to track whether o
548
BIO220H1 Lecture Notes - Lecture 12: Phenology, Pleiotropy, Pronghorn
Bio220 lecture 12: climate effects on organisms, phenology, and interactions. Sometimes changes in the environment happens slow enough for migration to
370
BIO220H1 Lecture Notes - Lecture 16: Twin, Phenotypic Plasticity, Reaction Norm
Important points to know in this lecture: genes and environment can influence phenotypes and behaviours, natural selection shapes behaviour just like i
632
BIO220H1 Lecture Notes - Lecture 17: Case Competition, Natural Selection, Gamete
~ 90% of our genes are shared between male and females. These shared genes are expressed differently in some ways. Most different is in gonads, some in
531
BIO220H1 Lecture Notes - Lecture 18: Satin Bowerbird, Natural Selection, Hangingfly
Bio220 lecture 18: sexual selection and mate choice. Strong sexual selection in traits with the sex that has the highest reproductive variance. High re
446
BIO220H1 Lecture Notes - Lecture 19: Queen Ant, Cooperative Breeding, Eusociality
Meerkat and ground squirrels make alarm calls when they see a predator coming. this will increase the risk of the caller, but will increase the fitness
442
BIO220H1 Lecture Notes - Lecture 20: Carotenoid, Kentish Plover
Small analogy: think of parent-offspring as a conflict over money. Your parents do not want to give too much. *your parents will weight these benefits
351
BIO220H1 Lecture 21: Extended phenotypes
An observable trait or features of an organism. Phenotype (z) involves both genetic and environment influence. Things that are produced by the organism
474
BIO220H1 Lecture Notes - Lecture 22: Viral Hemorrhagic Fever, Rhinovirus, Drug Resistance
Application of evolutionary principle into health and disease. Ask why (ultimate) rather than how (proximate) questions. Disease requires an ultimate e
355
BIO220H1 Lecture Notes - Lecture 23: Marginal Utility, Marginal Cost, Influenza A Virus
467
BIO220H1 Lecture Notes - Lecture 24: Avian Malaria, Drug Resistance, Antimicrobial Resistance
Fever, chills, anemia (loss of red blood cells) Kill the parasite within us drug treatments. Decrease contact between humans and vector bed nets. First
369
BIO220H1 Lecture Notes - Lecture 25: Display Size, Mortality Rate, Antagonistic Pleiotropy Hypothesis
Proximate cause: progressive degeneration of the soma. Degeneration of the soma impaired function (sight, strength, speed, etc ), or increased disease
379
BIO220H1 Lecture Notes - Lecture 26: Smallpox Vaccine, Cirrhosis, Edward Jenner
Memory cells form to improve immune response the next time the body encounter a similar antigen. Last case in canada was in 1946 and in the world in 19
