Multiple Choice

Which statement best explains how genetic traits are inherited according to modern genetics?

Genetic traits are inherited only through proteins present in the cytoplasm.

Genetic traits are acquired during an organism's lifetime and then transmitted to offspring.

Genetic traits are determined solely by environmental factors and not by DNA.

Genetic traits are passed from parents to offspring through DNA molecules that carry genetic information.

Verified step by step guidance

Understand that modern genetics explains inheritance through the transmission of genetic information encoded in DNA molecules from parents to offspring.

Recognize that proteins in the cytoplasm do not carry the hereditary information that determines genetic traits; instead, they are products of gene expression.

Acknowledge that traits acquired during an organism's lifetime (acquired characteristics) are generally not inherited because they do not alter the DNA sequence in germ cells.

Note that while environmental factors can influence the expression of traits, the underlying genetic information is encoded in DNA and is the primary determinant of inherited traits.

Conclude that the best explanation is that genetic traits are passed from parents to offspring through DNA molecules, which carry the genetic information necessary for inheritance.
