GED Sample Questions: Genetics Science Questions

By Murray Shukyn, Dale E. Shuttleworth, Achim K. Krull

The Science portion of the GED will expect that you have the equivalent of a high school student’s knowledge when it comes to genetics. Take a look to see what kinds of questions you might encounter.

The questions in this article refer to the following passage.

Heredity, Then and Now

How often have you seen a young child and said, “She takes after her parents”? Many traits in a child do come from her parents. Physical and other characteristics, such as hair color and nose shape, are transmitted from one generation to the next. These characteristics, passed from one generation to the next, exist because of genetic code.

The first scientist to experiment with heredity was Gregor Mendel during the 19th century. Mendel experimented with pea plants and noted that characteristics appearing in “child” plants were similar to the “parent” plants. Mendel hypothesized that these characteristics were carried from generation to generation by “factors.”

It took many years of research to understand why children often look like their parents, but genetic code is now the basis of the study of heredity.

  1. According to the passage, _________ is a primary determinant for characteristics of the next generation.

  2. The factors that Mendel hypothesized carried traits from one generation to the next is

    • (A)traits

    • (B)protons

    • (C)genetic code

  3. If you want to grow monster-sized pumpkins, from what kind of pumpkins do you want to get seeds to increase the probability of growing larger-than-average pumpkins?

    • (A)orange pumpkins

    • (B)monster-sized pumpkins

    • (C)larger-than-average pumpkins

    • (D)healthy pumpkins

Answer Key

  1. heredity.

    The passage states that heredity determines the characteristics of the next generation.

  2. C. genetic code.

    The passage states, “These characteristics, passed from one generation to the next, exist because of genetic code.” Thus, the best answer is genetic code.

  3. monster-sized pumpkins.

    If children inherit the traits of their parents, you want the desired traits of your child pumpkin to be a part of the traits of the parent pumpkins. Monster-sized pumpkin seeds (Choice [B]) have a better chance of producing extra large pumpkins than do the seeds from a regular-sized pumpkin.
