In tomatoes, a heterozygous plant with green leaves and red fruit is crossed with a recessive plant having mottled leaves and yellow fruit. The following distribution of offspring is observed: green leaves, red fruit 25% green leaves, yellow fruit 25% mottled leaves, red fruit 25% mottled leaves, yellow fruit 25% What conclusion can be made regarding the loci for leaf color and fruit color?

very easy

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.
