Question 19 In pea seeds, yellow color (Y) is dominant to green color (y), and around shape (R) is dominant to a wrinkled shape (r). A dihybrid cross between a true breeding plant with yellow, round seeds (YY RR) and
a true-breeding plant with green, wrinkled seeds (vyrr) results in an F, generation of plants with yellow, round seeds. Crossing two F, plants produces an F, generation with approximately nine times as many
plants with yellow, round seeds as plants with green, wrinkled seeds.
Which of the following best explains these results?
The allele pairs of each parent stay together, resulting in gametes that are identical to the parents.

miss jennifer is buying pencils in packs of 12, notebooks in packs of 16, and red pens in boxes of 20. she needs to have the same number of pencils, notebooks, and red pens. how many packs of each type should she buy?

answer mine : )

the answer is c on e2020, bud.

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.
