Which statement best describes the law of independent assortment in genetics?
A
Alleles of different genes are distributed independently of one another during gamete formation.
B
Genes located on the same chromosome always assort independently.
C
Dominant alleles always segregate together during meiosis.
D
Each gene is inherited together with its homologous chromosome.
Verified step by step guidance1
Understand that the law of independent assortment states that alleles of different genes are distributed independently of one another during gamete formation.
Recall that this law applies to genes located on different chromosomes or genes far apart on the same chromosome, allowing for random combinations of alleles.
Recognize that genes located close together on the same chromosome tend to be inherited together due to linkage, so they do not always assort independently.
Note that dominant alleles do not necessarily segregate together; segregation depends on the behavior of homologous chromosomes during meiosis, not dominance.
Remember that each gene is inherited with its homologous chromosome, but independent assortment refers to how different gene pairs segregate independently, not the inheritance of a single gene.
