Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>

A functional adaptation is any adaptation that helps an organism survive. 
Hence, the correct answer is option D - the color and shape of a flounder allow it to camouflage. 
This adaptation allows animals to camouflage with colors, patterns, and body shapes. Both predators and preys can process camouflage.
