Which of the following statements about independent assortment of genes is correct?
A
Genes located on different chromosomes assort independently during meiosis.
B
Independent assortment occurs during DNA replication.
C
Genes that are close together on the same chromosome always assort independently.
D
Independent assortment only applies to prokaryotic organisms.
Verified step by step guidance1
Recall the principle of independent assortment, which states that genes located on different chromosomes are distributed independently of one another during meiosis.
Understand that independent assortment occurs during meiosis, specifically in metaphase I, when homologous chromosome pairs align randomly at the cell equator, not during DNA replication.
Recognize that genes located close together on the same chromosome tend to be inherited together due to genetic linkage, so they do not always assort independently.
Note that independent assortment is a fundamental concept in eukaryotic genetics and does not apply to prokaryotic organisms, which do not undergo meiosis.
Conclude that the correct statement is: 'Genes located on different chromosomes assort independently during meiosis.'
