QUESTION 2 2.1 Lizards of a certain species are usually brown in colour. As a results of continental
drift the population was split by the sea. A mutation in one gene for body colour IN
black Lizards resulted in red or black Lizards forming. Over many generations black
Lizards mated with red Lizards and infertile offsprings were produced. While when
brown lizards were brought together, the two could not interbreed at all since some
were active in the day and some in the night.
When brown Lizards mated with black Lizards, fertile offsprngs were produced.​

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

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.
