Amoeba Sisters Video Recap-DNA, Chromosomes, Genes, And Traits: An Intro To A Picture Says It! 18. Explain What This Image Represents Regarding Where Your Entire DNA Code Can Be Found. 19. Apply Your Understanding Spike Is Not A Clone Of His Father. He Inherited DNA From Both Of His Parents. Chromosomes Are Condensed Units Of DNA. If Spike Has 36
The Correct Answer and Explanation is:
Correct Answers:
18. This image represents how your entire DNA code can be found inside the nucleus of almost every cell in your body. Inside the nucleus, the DNA is organized into chromosomes, which are tightly coiled and condensed structures made of DNA and proteins. These chromosomes contain genes, which are specific sequences of DNA that determine your traits.
19. If Spike has 36 chromosomes, that means he inherited 18 chromosomes from each parent. This illustrates how genetic material is passed on — half from the mother and half from the father — leading to genetic diversity. Since Spike received DNA from both parents, he is not a clone of either.
300-Word Explanation:
In the Amoeba Sisters video “DNA, Chromosomes, Genes, and Traits,” the concept of genetic information is simplified using a visual overview. The image in question (from question 18) likely illustrates a hierarchical structure: starting with the cell, which contains a nucleus, and inside the nucleus are chromosomes. These chromosomes are made of DNA (deoxyribonucleic acid), which contains the instructions for building and operating an organism. This DNA is packaged into genes, which are specific segments of DNA that code for proteins and determine traits like eye color, height, or blood type.
Every human (and animal like Spike) has cells with this complete DNA code in the nucleus. The full set of DNA is referred to as the genome, and it is nearly identical in all cells of the body, though only certain genes are “turned on” or expressed in different cell types.
Now, regarding question 19, Spike has 36 chromosomes in total, which means he received 18 chromosomes from his mother and 18 from his father. This pattern of inheritance is consistent with sexual reproduction, where gametes (egg and sperm) each contribute half the chromosomes. This mixture is why Spike is not a clone of his father — his genome is a unique combination of both parental DNA. While he may resemble his father in some ways, the presence of maternal DNA ensures he has his own distinct traits.
This process of genetic recombination increases diversity within a species and helps explain why offspring are not exact replicas of their parents.
