50/50
you see, the coin only has 2 sides
Also, you're flipping it twice
therefore, the probability is matched up and you have a 50/50 chance of getting heads at least 1 of those 2 times
(Hope it helped ^_^)
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

<h3>What is thermoregulation ?</h3>
Mammals regulate their body temperature carefully and independently of their environment through a process called thermoregulation. A method of maintaining a constant internal temperature necessary for survival is temperature regulation.
- Poikilothermy and homeothermy are the two main reactions to changing environmental temperatures (TA) that animals display.
- Progesterone tends to promote heat conservation and higher body temperatures, whilst estradiol tends to increase heat dissipation, and both hormones have an impact on thermoregulation both centrally and peripherally.
