Put all the candies used in Problem 40 into a single mound and then divide them into four equal piles, this time being sure that the frequency of each color is the same in each pile. Label two of these piles 'male' and the other two 'female.' Half of the group will take one male and one female pile, and the other half of the group will take the other two piles. Each half of the group will carry out its own experiments: Determine the frequency of each candy color in the total of 25 draws (a total of 50 candies) and compare these frequencies with the original frequencies of the colors in the pile.

Which of the following best explains the difference between two alleles of the same gene?
A
They are always located on different chromosomes.
B
They have variations in their nucleotide sequences.
C
They are expressed only in somatic cells.
D
They code for entirely unrelated proteins.

1
Understand that alleles are different versions of the same gene located at the same position (locus) on homologous chromosomes, not on different chromosomes.
Recognize that the primary difference between alleles lies in variations in their DNA nucleotide sequences, which can lead to differences in the gene's function or expression.
Note that alleles are not restricted to expression in somatic cells; they can be expressed in various cell types depending on the gene.
Realize that alleles of the same gene code for proteins that are related in function, not entirely unrelated proteins, since they come from the same gene locus.
Conclude that the best explanation for the difference between two alleles of the same gene is the variation in their nucleotide sequences.
