Environmental factors can influence an organism’s traits over time. This means the changing environment makes certain
traits (like skin color) become a dominant trait for a species.
19. Due to global warming, polar bears, who hunt on the ice of the frozen ocean much of the year, are starting to get
stuck on icebergs as the ice melts. The bears who can swim to land or more ice the best will live. Those who don’t swim
as well will drown. The best swimmers will be around to mate and these muscles may be passed to their offspring.

20. Giraffes living in the jungle have darker spots to blend in with the shaded area than their relatives living in the
grasslands. The grassland giraffes have lighter coats and spots to blend in with the grass. The jungle giraffes with light
coats and spots tend to get eaten when they are young by predators because they are more easily seen. So the ones
that live to adulthood in the jungle tend to be the darker ones and pass their genes down to their offspring.
Would this be an environmental factor affecting a species’ traits over time? (yes, no)
21. A fire in the forest causes doves to fly away to a new area and start eating grass seeds rather than the tree seeds
they were used to eating.
Would this be an environmental factor affecting a species’ traits over time? (yes, no)

I.Gene coding involves sets of 3 nucleotide bases. For a brief overview, there are nucleotides that make these. They are
A, T, C, and G.
Again, they come in sets of 3.
The sets of 3 make up proteins.
Mutations occur in genes when a nucleotide has an error in it as it reproduces.
Look at the following:
AAT CAG GCT
When this replicates, the end result should be the same, which is:
AAT CAG GCT
II. Sometimes one nucleotide base replaces another. This is called a substitution.
In the following sets, look at the first group. Then in the second group, circle the nucleotide that was a substituted
mutation.
1.AAT CAG GCT 2. ATA CGA AAC 3. TCT TGT AGT
AAC CAG GCT ATA CGA TAC ACT TGT AGT
III. Other types of mutations that change the numbers all the way are called frameshifts. These will make the numbers
incorrect. There are insertions where a nucleotide has been added and this moves the position of each protein set.
Ex. ATA CGA AAC
ATA CCG AAA
The middle C in in the second set is an insertion. Notice that the letters coming after it are in the same order, but they
now form different 3 letter proteins. This causes a mutation.
IV. If a nucleotide is missing during replication, it is a deletion.
ATA CGA AAC
AAC GAA ACT Notice that the 2nd letter in the first set, the T, is missing from the second set. This causes the
proteins to be different and also causes a mutation.
Look at each set. Circle where the change occurred in the second set. Then tell if the replication has had a deletion or an
insertion frameshift.
4. AAC CAG GCT 5. TCT TGT AGT 6. ATA CGA AAC
AAC CGG CTA TCT TAG TAG AAC GAA ACA
(insertion, deletion) (insertion, deletion) (insertion, deletion)
V. Tell whether the following have substitution, deletion, or insertion mutations.
7. TCT TGT AGT 8. TCT TGT AGT 9. TCT TGT AGT
ACT TGT AGT TTT GTA GTA TAC TTG TAG
(insertion, deletion, substitution) (insertion, deletion, substitution) (insertion, deletion, substitution)
Incomplete Dominance: Neither trait dominates over the other. There is a mixture of the phenotypes.
Ex. Red + Yellow = orange
Tell what the phenotype is for the following incomplete dominant crosses:
1.Black + White = ________________
2. Red + Blue = ___________________
3. Blue + Yellow = ______________________
4. Look at the following Incomplete Dominance Punnett square. R = red, r = white.
Rr x Rr RR = red
Rr = pink
rr = white
Write what the phenotype is for each genotype (HINT- It’s already given above. I just need you to know this for 4-15):
4. RR = ______________
5. Rr = _______________
6. rr = ________________
Work out the Punnett squares for Incomplete Dominance for these snapdragon flowers. Use 4-6 to tell the phenotypes.
Rr x rr
7. # with the phenotype for red _______
8. # with the phenotype for pink ______
9. # with the phenotype for white _____
Make a Punnett square using RR x rr.
10. # with the phenotype for red _______
11. # with the phenotype for pink ______
12. # with the phenotype for white _____
---------------------------------------------------------------------------------------------------------------------------------------------
Make a Punnett square using RR x Rr.
13. # with the phenotype for red _______
14. # with the phenotype for pink ______
15. # with the phenotype for white _____
-------------------------------------------------------------------------------------------------------------------------------------------
Co-Dominance: means both alleles have the same strength. Neither dominates over the other. Both traits
will show up in the offspring.
Ex: A red cow + a white cow = a white cow with red spots (AKA a roan cow)
RR = red
RW = spotted
WW = white
Work out the following Punnett squares for Co-
Dominance in cow colors and tell what the
phenotype is for each.
Work out the following Punnett squares for Co-Dominance in cow colors and tell how many have each
phenotype.
Spotted x White: RW x WW
17. _______ are white
18. _______ are red
19. _______ are spotted
----------------------------------------------------------------------------------------------------------------------------------------------
Spotted x Spotted: RW x RW
20. _______ are white
21. _______ are red
22. _______ are spotted
---------------------------------------------------------------------------------------------------------------------------------------------
Red x Spotted: RR x RW
23. _______ are white
