A gene is to a chromosome as ?

1) a pea is to a pod
2)a front is to a back
3)a bike is to a car
4)a building is to a window

I think # 1

Thanks.

Yes, you're correct.

A chromosome is composed of several genes as segments.

You're correct! The analogy "a gene is to a chromosome as a pea is to a pod" is a suitable comparison. In both cases, a gene is a smaller component/part of a chromosome, just like a pea is a smaller component/part of a pod.

You're on the right track! The relationship between a gene and a chromosome can be compared to the relationship between a pea and a pod. Just as a pea is a small part or segment of a larger structure, a gene is a specific segment of DNA in a chromosome. Therefore, option 1) "a pea is to a pod" is the most appropriate analogy in this case. Well done!
