Choose all statements that constitute key tenets of the chromosome theory of inheritance.
A) Chromosomes are copies of the genetic material that are used to make proteins and are then destroyed.
B) Chromosomes contain the genetic material.
C) Chromosomes are contributed by the maternal parent only.
D) Chromosomes are replicated and transmitted during inheritance and during development.
E) Most cells are diploid, with two copies of each chromosome.
F) Gametes contain two copies of each chromosome so there is a backup copy if one is damaged.
G) During gamete formation, chromosomes segregate independently.
H) Each parent contributes one complete set of chromosomes.
I) Certain chromosomes are linked together, so that genes that work together are transmitted together.

Question

Quizplus · Accepted Answer

The chromosome theory of inheritance proposes that chromosomes contain the genetic material that is transmitted from parents to offspring, and that chromosomes are replicated and transmitted during inheritance and development. This theory also states that most cells are diploid, with two copies of each chromosome, and that during gamete formation, chromosomes segregate independently. Additionally, each parent contributes one complete set of chromosomes. Statement A is incorrect, as chromosomes are not destroyed after making proteins. Statement C is incorrect, as both parents contribute chromosomes. Statement F is incorrect, as gametes only contain one copy of each chromosome. Statement I is partially correct, as certain genes are linked together on the same chromosome, but not all chromosomes are linked together.
