3
Allele: The variant form of a gene.
What is a variant?
Nice! Let's write it.
4
The different versions of Loki were called variants.
5
Word Cloud
Let's say the gene is hair color. What are my allele options?
6
If the gene is hair color, then my alleles could be:
-Brown
-Blonde
-Black
-Red
Nice! Let's write it.
7
Multiple Choice
Is a dominant allele going to be strong or weak?
Strong
Weak
8
Multiple Choice
What letter would best represent a dominant allele?
A
a
9
Multiple Choice
What letter would best represent a recessive allele?
A
a
10
Find letters in your bucket that would represent a dominant allele and a recessive allele and glue them down.
Stuck? Ask a teacher!
Nice! Let's glue it.
11
Multiple Choice
What does the prefix "hetero" mean?
Same
Different
12
Multiple Choice
What does the prefix "homo" mean?
Same
Different
13
Biology Examples:
Homozygous
Heterozygous
Good! Let's add these to our prefix list.
What are some other words that we know with these prefixes?
Write a biology sentence for each word, using the biology example words to the left. Be sure to underline your prefix and the meaning within your sentence!
14
Who do you get your alleles from?
How many alleles do you get for each gene?
Let's think for a second...
15
Fill in the Blanks
Type in the letters that you think could represent someone with heterozygous alleles. (Use the letter A)
16
Multiple Choice
Which would represent alleles that are homozygous dominant?
AA
Aa
aa
17
Multiple Choice
Which would represent alleles that are homozygous recessive?
AA
Aa
aa
18
Find letters in your bucket that would represent a heterozygous and homozygous alleles and glue them down.
Stuck? Ask a teacher!
Nice! Let's glue it.
19

They have brown eyes.
They are tall.
Heterozygous
23
Word Cloud
Write me some examples of phenotypes.
24
Find pictures in your bucket that would represent a genotype
and a phenotype and
glue them down.
Stuck? Ask a teacher!

25
Multiple Choice
Let's assume in pea plants, yellow peas are dominant to green. What letter can we use to represent the allele for yellow?
G
g
26
Multiple Choice
So, Yellow (G) is dominant and Green (g) is recessive.
Remind me a again, what's a genotype?
The genetic information, like Aa or heterozygous
The physical parts, like being green or yellow
27
On page 2 of your packet, fill out the four boxes for genotype.
When you are done, get a teacher to check your answers.
Nice! Let's practice.
28
Multiple Choice
So, Yellow (G) is dominant and Green (g) is recessive.
Remind me a again, what's a phenotype?
The genetic information, like Aa or heterozygous
The physical parts, like being green or yellow
29
On page 2 of your packet, fill out the three boxes for phenotype.
When you are done, get a teacher to check your answers.
Nice! Let's practice.
30
Multiple Select
There's a challenge question at the end. Let's answer it.
What two genotypes would result in the same phenotype?
AA
Aa
aa
31
Fill in the Blanks
Good! So Yellow Peas (G) are dominant to Green Peas (g). What color would AA or Aa make?
Type answer...
