In conducting a common garden experiment with ragweed plants from two populations you calculate phenotypic and genotypic variance estimates on plant height. What is the broad sense heritability of plant height in the two populations

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.

b is dominant over the allele for the white fur.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
