Understanding Independent Assortment
Multiple Choice
In the context of independent assortment, what percentage of genetic information does an offspring inherit from each parent?
A
25% from each parent
B
75% from the father and 25% from the mother
C
100% from the mother and 0% from the father
D
50% from each parent
Verified step by step guidance1
Understand the principle of independent assortment, which states that alleles of different genes are distributed independently of one another during gamete formation.
Recall that in sexual reproduction, an offspring receives one set of chromosomes from each parent, meaning half of its genetic material comes from the mother and half from the father.
Express this concept mathematically: the proportion of genetic information inherited from each parent is \(\frac{1}{2}\) or 50%.
Recognize that this 50% inheritance from each parent applies to the entire genome, assuming no unusual genetic events like uniparental disomy.
Conclude that the offspring inherits 50% of its genetic information from the mother and 50% from the father, consistent with Mendelian genetics.
