The answer is A
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
<span>It is process through which plants and other photoautotrophs generate carbohydrate and oxygen from carbon dioxide, water and light energy in chloroplast. It is two stage reaction-
1.Light dependent reaction- in this sunlight is absorbed by chlorophyll and converted into chemical energy and stored in the form of NADPH and ATP. It takes place in thylakoid membrane in chloroplast.
2.Light Independent Reaction- in this energized electrons from the light dependent reaction provides the energy to form carbohydrate from carbon dioxide molecules. It is known as Calvin cycle.</span>
Answer:
The correct answer would be a. the sum of all genetic traits in a population’s individuals at a given time.
A gene pool is defined as a sum total of all the genes present in an inter-breeding population at a specific time.
It includes all the alleles of all the loci within the genes of a interbreeding population or species.
The composition of the gene pool of a population can change with course of a time due to evolution.
A large and diverse gene pool enhances the ability of a population to adapt, survive and evolve in a nature.
Well sickle cell disease requires two homozygous recessive alleles so you would have the disease but if your'e heterozygous you have the sickle cell trait.
