Does anyone know if the 2015 practice exam was released? They usually release them but I don’t think they did this year.
Hi, does anyone know if Hardy-Weinberg and genetics will be topics in the FRQs? My bio teacher told me that they typically include one FRQ on sources of genetic variation, so be sure to study that. Also, if anyone could post additional study resources that they found, it would be greatly appreciated 
Don’t worry guys, we’re all gonna do amazing!!!
here is the practice test released in 2014, it seems really helpful to me…

What percent equates to a 5?
hardy weinberg will most likely be asked in the grid ins not frq
very high chance there will be a genetics frq though
I don’t think so. Im taking 2014 tomorrow most likely… Currently watching Bozeman videos and writing notes on it and its helping a lot with sticking info in my head and using those concepts for analysis
Do you think they would ask anything about natural selection and how it affects phenotypes directly and genotypes indirectly and/or the steps to genetically clone an animal?
Hardy Weinburg will most likely be a grid-in be very familier with the labs if you want to do really well on the first frq .
by labs you mean investigations right? i think thats what theyre referred to as in barrons and cliffnotes review books
Yep I took this last year and totally bombed Q1 bc I had no idea how to calculate standard deviation or draw the graph .
for yall who already took ap bio- did u have enough time to finish and check answers in MC
Isn’t the formula for standard deviation on the formula sheet?
@DyrannosaurusRex it is but the ap exam was first time trying so I didn’t what to plug in where lol
@awkplatypus I finished but I didn’t have time to check my answers . Other people who took it last year on here finished it with 30 mins left to check their work so I guess it depends on the person .
can someoone explain to me how to do this question?
A certain species of plant has four unlinked
genetic loci, W, X, Y, and Z. Each genetic locus
has one dominant allele and one recessive allele.
For a plant with the genotype WwXxYyZz, what
is the probability that the plant will produce a
gamete with a haploid genotype of Wxyz ? Give
your answer as a fraction or as a value between 0
and 1, to four decimal places.
so was time ever a big problem in general cuz i heard theres alot of reading passages?
@instanteco , I think its 1/21/21/2*1/2=1/16, you’re just using the laws of probability to calculate it? So there’s a 1/2 chance of the allele being a W, and 1/2 of it being x, and 1/2 of it being y, and 1/2 of it being z. If it’s “and” you multiply, if it’s “or” you add.
I think the biggest problem in general was a proigree table wasn’t bad not including the grid-ins . Also make sure you understand how to do a chi square for the grid-ins not sure if it will be there this year bc it was there last year . @awkplatypus
@InstantEco Given WwXxYyZz, you have to split the genes up. So first see what the probability of getting a W from Ww is (.5), then the probability of getting x from Xx (.5), then the probability of getting y from Yy (.5), then the probability of getting z from Zz (.5). Once you have the individual probabilities, you just multiply. .5 x .5 x .5 x .5 = .0625
what are you guys reviewing right now? I don’t know what to do…I finished Barron’s book.
