The observed distribution of alleles into gametes is an illustration of which genetic principle?
A
linkage
B
incomplete dominance
C
codominance
D
independent assortment
Verified step by step guidance1
Step 1: Understand the question is asking about the genetic principle illustrated by the observed distribution of alleles into gametes.
Step 2: Recall that 'linkage' refers to genes located close together on the same chromosome that tend to be inherited together, which affects allele distribution.
Step 3: Recognize that 'incomplete dominance' and 'codominance' describe patterns of phenotype expression, not the distribution of alleles into gametes.
Step 4: Identify that 'independent assortment' is the principle stating that alleles of different genes segregate independently during gamete formation, leading to a variety of allele combinations.
Step 5: Conclude that the observed distribution of alleles into gametes exemplifies the principle of independent assortment.
