The genotype of heterozygous would be PpLl.
Formed gametes are PP Pl pL pl
Parents: PpLl x PpLl
<span>The correct answer is
B. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash)</span>
Polka-dot tails and long eyelashes: PPLL PPLl PpLL PpLl PPLl PpLl PpLL PpLl PpLl
<span>Polka-dot tails and short eyelashes: PPll Ppll Ppll</span>
<span>Solid tails and long eyelashes: ppLL ppLl pp Ll</span>
<span>Solid tail and short eyelash: ppll</span>
Chemical reaction occurring in cells.
Cells use up the food to make energy. Heat is also released during the process...
So, 'chemical reactions occuring in cells' is the right answer.
Answer:
Breed "pure" mice with known genotypes that exhibit specific fur colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur color are reported every time a pair of mice breed. Punnett squares can be used to predict results.
Explanation:
Unfortunately this question is incomplete as it does not provide any choices. However, there are certain ecological factors that can cause a population of mice to decrease quickly. One is an increase in predation. Many carnivorous animals prey on mice, including birds of prey, foxes and various other predacious mammals, as mice are small and high in number. This means a lot of mice are removed from the population through predation. Any increase in predator pressure could quickly disturb the balance in the mice population. Another factor is a disease. Some diseases can seriously deplete populations of animals, with the remaining hardier individuals developing immunity.
