Frate_Raper Posted April 18, 2005 Share Posted April 18, 2005 I skipped 2 classes about setting up Punnet tables for plant genetics and I'm working on my take home exam for my Botany for Gardening class and I'm stuck,the inter web hasn't been much help I need some one to explain this shit. Yeah Yeah i'm studying gardening fuck off Quote Link to comment Share on other sites More sharing options...
JohnnyHorton Posted April 18, 2005 Share Posted April 18, 2005 i'm not sure how in depth whatever you're taking is but i do know that all a punnet square does is take each chromosome of the two species being crossed and shows all the possible outcomes of reproduction is that along the lines of what you're doing or more indepth?

heavyLox Posted April 19, 2005 Share Posted April 19, 2005 What is a Punnett Square and how do we use it? A Punnett Square is simply a tool to help you understand how alleles are passed to the next generation. It enables you to follow each parental allele as it could get passed to the next generation. Use your book, the book CD, and the following figure to help you along here with a monohybrid cross. All you have to do is know the genotypes of the parents-- that tells you which alleles each parent could offer to the next generation. The alleles they could give are what you write along the side and top of the square; once you figure out what letters to write along the side and the top of your square, it is easy to fill in. Here's a description for how to do a parental generation monohybrid cross between individuals that are purebred. Quote Link to comment Share on other sites More sharing options...

Guest sneak Posted April 19, 2005 Share Posted April 19, 2005 my knowledge of plant biology amounts to understanding photosynthesis and knowing the words "xilem" aand "flowem". Quote Link to comment Share on other sites More sharing options...

JohnnyHorton Posted April 20, 2005 Share Posted April 20, 2005 heavy lox posted what i was talking about monohybrid isn't so bad... its keeping track of 2cnd and 3rd gen dyhybrid crosses that get tough punnet squares need good book keeping Quote Link to comment Share on other sites More sharing options...
