some dioecious species have the xy genotype for male and xx for female. after double fertilization, what would be the genotypes of the embryos and endosperm nuclei?

im not in connections yet but i might can you some questions. what grade are you in?

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.
