In a population of 100 diploid individuals, how many total alleles are present for a single autosomal gene?
A
100
B
400
C
200
D
50
Verified step by step guidance1
Recognize that each individual in the population is diploid, meaning they have two copies (alleles) of each autosomal gene.
Identify the total number of individuals in the population, which is given as 100.
Calculate the total number of alleles by multiplying the number of individuals by the number of alleles per individual: $100 \times 2$.
Understand that this calculation gives the total number of alleles for the single autosomal gene in the entire population.
Express the final formula for total alleles as $\text{Total alleles} = 2N$, where $N$ is the number of diploid individuals.
