Dragon Genetics Worksheet #1 Key from University of Pittsburgh at Bradford Biology Lab.

Let’s go step by step through each question using the Dragon Key provided.

Question 1: What letters are used to represent wing color?

Look at the key:
- R = RED WINGS (dominant)
- r = yellow wings (recessive)

So, R and r are used for wing color.

✔ Answer: R and r

---

Question 2: What letters are used to represent neck length?

From the key:
- N = LONG NECK (dominant)
- n = short neck (recessive)

So, N and n are used for neck length.

✔ Answer: N and n

---

Question 3: The letter “Y” is used as a symbol to represent the Y chromosome and the secondary sex characteristic of ear frills.

Check the key:
- X = X chromosome / no ear frills
- Y = Y chromosome / ear frills present

Also note: XY = male → so males have ear frills.

This statement is correct based on the key.

✔ Answer: True (or just confirm it's accurate — since it’s not a fill-in, but part of instructions, we’ll move on)

---

Question 4: The letter “e” is used to represent white eyes.

From the key:
- E = RED EYE
- e = white eye

Yes, lowercase “e” = white eyes.

✔ Answer: Correct

---

Now, Questions 5 and 6 ask us to list traits from the key.

Remember:
- Uppercase = dominant trait
- Lowercase = recessive trait

---

Question 5: List six dominant traits shown in the key.

Dominant traits are coded by uppercase letters. Let’s pick any six:

Examples:
1. N = LONG NECK
2. H = HORN PRESENT
3. G = GREEN BODY
4. S = SPIKES ON END OF TAIL
5. T = THREE TOES
6. B = BLACK TAIL SPIKES

(You could also choose E, F, L, R, W, K — all uppercase ones.)

✔ Any six uppercase-letter traits are acceptable.

---

Question 6: List six recessive traits shown in the key.

Recessive traits are coded by lowercase letters. Pick any six:

Examples:
1. n = short neck
2. h = horn absent
3. g = grey body
4. s = no spikes on end of tail
5. t = four toes
6. b = red tail spikes

(Others: e, f, l, r, w, k — all lowercase.)

✔ Any six lowercase-letter traits are acceptable.

---

Final Answers:

1. R and r
2. N and n
3. (Statement is correct — no answer needed beyond understanding)
4. white eyes
5. Example: LONG NECK, HORN PRESENT, GREEN BODY, SPIKES ON END OF TAIL, THREE TOES, BLACK TAIL SPIKES
6. Example: short neck, horn absent, grey body, no spikes on end of tail, four toes, red tail spikes

Final Answer:
1. R and r
2. N and n
3. [Correct statement — no written answer required]
4. white eyes
5. LONG NECK, HORN PRESENT, GREEN BODY, SPIKES ON END OF TAIL, THREE TOES, BLACK TAIL SPIKES *(any 6 dominant traits)*
6. short neck, horn absent, grey body, no spikes on end of tail, four toes, red tail spikes *(any 6 recessive traits)*
