Ran in 3 of the last 7 terms. Winter 2027: not on the schedule. Spring 2027: schedule not out yet.
This course will provide an in-depth coverage of reproductive biology in a range of mammalian species. Emphasis will be on the principles underlying the regulation of key reproductive processes, from the whole animal to the molecular level. Topics will include applications of these principles to human and veterinary medicine, and ethical problems posed by some reproductive technologies.

my favourite course of my whole undergrad. so fun and interesting, especially if you like physiology.
similar vibes as 373 but more niche and its about everything heidi loves to talk about so she's at her best. i didnt like her in 130, in 373 she was good, in 473 she was great. she gets more unhinged and funnier every year.
breakdown was two midterms, a final, and a lab evry other week that was not super hard and neutral amount of interesting. short worksheet for each lab which i did in lab with my partner but you could do outside if you wanted more time.
would highly recommend as a 400 level bio course just bcz it was so interesting. requires a fair bit of studying but the test questions…Apr 2026 · liked itOn UW FlowRemove this
Taken F25, two midterms (20% & 25%) and final exam (30%), 5% in-class quizzes usually once a week, and lab assignments (4 x 4%) + lab quizzes ( 4 x 1%). I would argue this course is similar, maybe a bit harder than BIOL373, depending how you feel about the fully-written tests. They are not necessarily easy but if you put the effort into studying you'll do well. Lab assignments are straight-forward and easy to do well on, plus don't take too long! I thought this course was very enjoyable, its Heidi's bread and butter so she is very knowledgable and the comments and jokes she makes throughout were actually very entertaining. Would recommend, finished with a 93 (same as 373).

Taken Winter 2024, marking scheme is 75% midterms (20% test 1, 25% test 2 non-cumulative and 30% final exam cumulative). 5% weekly in person quizzes prorated to 5% if above 75%. 20% lab assignments 4x5%. The labs are biweekly and the assignments are very easy. It is possible to get over 90+ on each. The tests are completely long and short answer with no multiple choice. The content is divided up into online weekly content lectures you do at home and in person application units you go over in class. There is no textbook. The content is interesting. The difficulty is around the same as BIOL 373. Finished both classes with a mark in the low 90s.

not that hard, just ask questions and don't fall behind. definitely easier than BIOL 373. Really the best part was getting more unfiltered Heidi-isms than ever before.

The course was composed of 2 midterms, a lab component and a final exam. So this course was definitely content heavy. Everything overlaps and flow charts can definitely be made but it's not a class that's easy to cram for (but is possible). If you've had Heidi before you know that her thought process is a little scrambled and as are her notes, they don't make sense on their own so going to class is a must! Midterms were random as to what she thought was important but because it's all written you can bullshit through a bit. Lab component was stupid since there would be only one station for all these kids to go to, and there were assignments associated, some which took a while to complete.…

u/Eds0: “Biol 473 was fun, they don't change up the lab reports so you can probably find someone who did it last year and get a perfect mark on the reports (which is like worth 20% of your final grade). I would give you mine but I threw them away sorry m8.”
