Question

after examining his pea - plant data, which three conclusions did mendel reach?
a. a genes alleles must be inherited independently of each other.
b. traits acquired during an organisms lifetime are passed along to its offspring.
c. during reproduction, some kind of factor is passed from parent to offspring.
d. recessive traits are masked by dominant traits.

Explanation:

• Option A: Mendel's law of independent assortment states that alleles of different genes assort independently during gamete formation.
• Option C: Mendel proposed the concept of "factors" (now known as genes) that are passed from parents to offspring.
• Option D: Mendel observed that in a cross between two pure - breeding plants (one with a dominant trait and one with a recessive trait), the recessive trait was not visible in the F1 generation (dominant trait masked the recessive trait).

• Option B: This is Lamarck's theory of inheritance of acquired characteristics, which Mendel did not support. Mendel's work was based on the inheritance of pre - existing genetic factors.

Answer:

A. A gene's alleles must be inherited independently of each other.
C. During reproduction, some kind of factor is passed from parent to offspring.
D. Recessive traits are masked by dominant traits.
