Step 1:I'll solve this step-by-step, focusing on Mendel's law of segregation:
Step 2:: Understand the Law of Segregation
The law of segregation is a fundamental principle of genetics first described by Gregor Mendel. This law explains how alleles (gene variants) are passed from parents to offspring.
Step 3:: Analyze the Key Characteristics
The law of segregation states that: - Each organism has two copies of each gene - During gamete formation, these gene copies separate - Each gamete receives only ONE allele for each trait
Step 4:: Evaluate the Given Options
D. $$\text{Traits are passed independently of one another}$$ - Incorrect (describes independent assortment, a different law)
B. \text{Traits that are dominant mask traits that are recessive} - Incorrect (describes dominance, not segregation)
Step 5:: Explanation of the Correct Answer
Option C directly describes the core principle of the law of segregation: during gamete formation, each gamete receives only ONE allele for each trait.
Final Answer
Gametes carry one allele for each trait.
