Question

snurfle meiosis and genetics 2: diversity and dihybrid crosses
question- do you get it?
which of the following statements is true as a result of independent assortment?
a. the allele g will always be passed on with the allele f in the example cell shown.
b. the alignment of the top pair of chromosomes will not affect the alignment of the bottom pair.
c. green fur must always be passed on with the fin trait.
d. all of these are true.
score: 100 %
key:
g = yellow fur
g = green fur
f = no fins
f = fins
b = no wings
b = wings

Explanation:

To solve this, we analyze each option using the principle of independent assortment (alleles of different genes assort independently during meiosis, meaning the alignment of one chromosome pair doesn't affect another).

• Option A: Independent assortment means alleles can assort independently, so "G" won't always be with "F"—this is false.
• Option B: Independent assortment states that the alignment (metaphase orientation) of one pair of chromosomes does not influence the alignment of another pair. This matches the principle, so this is true.
• Option C: Traits (like green fur and fin) are controlled by different genes, so they don’t always assort together—this is false.
• Option D: Since A and C are false, D is false.

Answer:

B. The alignment of the top pair of chromosomes will NOT affect the alignment of the bottom pair.
