Multiple Choice

Which statement best describes heredity and its mechanism in mice?

Heredity refers to the physical traits that mice acquire during their lifetime and then pass on to their offspring.

Heredity is the process by which environmental factors alone determine the characteristics of mice.

Heredity is the process by which genetic information is passed from parent mice to their offspring through genes located on chromosomes.

Heredity is the random appearance of new traits in each generation of mice, unrelated to parental genetics.

Verified step by step guidance

Step 1: Understand the definition of heredity. Heredity is the biological process through which genetic information is transmitted from parents to offspring, influencing inherited traits.

Step 2: Recognize that acquired traits (those developed during an organism's lifetime due to environment or experience) are generally not passed genetically to offspring, so they do not define heredity.

Step 3: Identify that genes, which are segments of DNA located on chromosomes, carry the hereditary information responsible for traits in organisms such as mice.

Step 4: Note that environmental factors can influence the expression of traits but do not change the genetic information passed through heredity.

Step 5: Conclude that heredity involves the transmission of genetic information via genes on chromosomes from parent mice to their offspring, rather than random trait appearance or solely environmental influence.
