To answer your questions, let's start by crossbreeding two heterozygous curly-tailed pigs (Cc x Cc).
-
Punnett Square Analysis:
- Gametes: C (curly) and c (straight)
Creating a Punnett Square:
C c ----------------- | CC | Cc | C |----------|---------| | Cc | cc | -----------------
- From the Punnett Square, we find:
- 1 CC (homozygous dominant)
- 2 Cc (heterozygous)
- 1 cc (homozygous recessive)
-

Phenotypic Ratio of the F1 Generation:
- Curly tails (CC + Cc) = 3
- Straight tails (cc) = 1
Therefore, the ratio is:
- 3 curly : 1 straight.

Fill in the Ratio of Possible Phenotypes:
- Question Blank 1: 3
- Question Blank 2: 1
-
Genotypic Ratio of the F1 Generation:
- Homozygous dominant (CC) = 1
- Heterozygous (Cc) = 2
- Homozygous recessive (cc) = 1
Thus, the genotypic ratio is:
- 1 CC : 2 Cc : 1 cc.

Fill in the Ratio of Possible Genotypes:
- Question Blank 1: 1
- Question Blank 2: 2
- Question Blank 3: 1
-
Homozygous Recessive Count:
- From the Punnett Square, the number of homozygous recessive (cc) is 1.
-
Probability of Next Offspring Having Straight Tails:
- The probability of having straight tails (cc) is 1/4.
