when gregor mendel crossed true-breeding tall plants with true-breeding short plants, why was it impossible to observe segregation?

because all offspring plants would be the trait that is dominant

Because 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

lets 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.

ok a

A) 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

As thomaster explained it (I used a different definition I believe) the answer would be b

I could be wrong ^^ if so I apologize haha

B and D are correct i think
anonymous
  • anonymous
d
thomaster
  • thomaster
with 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

But i'd take D as answer
