Using the term "Allele" and the Passage below, Complete the Vocabulary Four Square Graphic Organizer



"An allele is a different version of a gene. Each gene comes in at least two forms, and these forms are called alleles. For example, a gene for eye color may have an allele for brown eyes and a different allele for blue eyes. You inherit one allele from each parent, and the combination you receive helps determine what trait you will show. Some alleles are dominant, meaning they show up even if only one copy is present, while other alleles are recessive and need two copies to appear."

Answer 1

Here’s a completed Four-Square organizer for the term "Allele."

Square 1 (Definition)
An allele is a different version of a gene. You inherit one allele from each parent, and combinations of alleles help determine traits. Some alleles are dominant (show if only one copy is present) and others are recessive (need two copies to appear).

Square 2 (Sentence — 7 or more words)
You inherit one allele for each gene from parents.

Square 3 (Synonym)
Variant

Square 4 (Picture — description and simple ASCII sketch)
Description to draw: Draw two parents and a child. For each parent, draw a chromosome pair with one allele labeled (e.g., B for brown, b for blue). Show the child’s chromosome pair receiving one allele from each parent (e.g., B from one parent and b from the other) and label the child’s trait (brown eyes if B is dominant).

Simple ASCII sketch:
Parent 1: [ B ] Parent 2: [ b ]
\ /
\ /
Child: [ B | b ] → Brown eyes (B is dominant)

You can color or label B as dominant (uppercase) and b as recessive (lowercase) to make the idea clearer.
