Best ResponseYou've already chosen the best response.2because all offspring plants would be the trait that is dominant

Best ResponseYou've already chosen the best response.1Because there was only one trait observed. So he was observing tall ( S ) and short (s) therefore the allele observed would not follow the segregation law which states that every allele segregates independently at meiosis I. So when he did it with 2 alleles ( lets say color in this case ) he got SsYy and they all segregated independently. Therefore giving every possibilities of offspring

Best ResponseYou've already chosen the best response.2lets say tall is dominant and short is recessive. You would cross TT with tt the offspring would be only Tt which means that all plants will be tall.

Best ResponseYou've already chosen the best response.0A) alleles for height do not segregate in the F2 B) alleles segregate only in the F2 generation C ) alleles segregate best when two tall plants are crossed D) alleles in the F1 must be Tt to have height variety in the F2

Best ResponseYou've already chosen the best response.1As thomaster explained it (I used a different definition I believe) the answer would be b

Best ResponseYou've already chosen the best response.1I could be wrong ^^ if so I apologize haha

Best ResponseYou've already chosen the best response.2B and D are correct i think

Best ResponseYou've already chosen the best response.2with TT x tt every offspring will be Tt so B is true but if the alleles in F1 are Tt you would have height variety in F2 So they're both correct

Best ResponseYou've already chosen the best response.2But i'd take D as answer
