To determine the percentage of calico (black and tan spotted) offspring from the given P (parental) square, we need to clarify the symbols used in the P square.
Assuming:
- B = Black fur allele
- T = Tan fur allele
In a calico cat, codominance means that both alleles are expressed, resulting in the characteristic black and tan pattern.
From the provided P square:
B B
----------------
B | BB | BB |
----------------
T | BT | BT |
----------------
The offspring combinations are:
- BB (Black)
- BB (Black)
- BT (Calico)
- BT (Calico)
Now, we count the phenotypes:
- Black: 2 (BB)
- Calico: 2 (BT)
We have a total of 4 offspring:
- 2 black and 2 calico.
Now, we calculate the percentage of calico offspring:
- Calico: 2 out of 4
- Percentage = (2 calico / 4 total) * 100% = 50%
Thus, the percentage of the offspring that will be calico (black and tan spotted) is 50%.
