Accepted Answer

### Question 1
# Explanation:
## Step1: Define Homozygous and Heterozygous
Homozygous (Ho) has two identical alleles (e.g., RR, aa), heterozygous (He) has two different alleles (e.g., Rr, Aa).
## Step2: Classify Each Genotype
- RR: Ho (two R)
- Yy: He (Y and y)
- AA: Ho (two A)
- ff: Ho (two f)
- II: Ho (two I)
- Aa: He (A and a)
- ww: Ho (two w)
- Gg: He (G and g)
- Tt: He (T and t)
- Aa: He (A and a)
# Answer:
RR: Homozygous (Ho)
Yy: Heterozygous (He)
AA: Homozygous (Ho)
ff: Homozygous (Ho)
II: Homozygous (Ho)
Aa: Heterozygous (He)
ww: Homozygous (Ho)
Gg: Heterozygous (He)
Tt: Heterozygous (He)
Aa: Heterozygous (He)

### Question 2a
# Explanation:
## Step1: Recall Dominance Rule
Dominant allele (capital) determines phenotype if present; recessive (lowercase) only if homozygous recessive. Green (G) is dominant over yellow (g).
## Step2: Determine Phenotype for Each Genotype
- GG: Homozygous dominant → Green
- Gg: Heterozygous (G is dominant) → Green
- gg: Homozygous recessive → Yellow
# Answer:
GG: Green pea pod color
Gg: Green pea pod color
gg: Yellow pea pod color

### Question 2b
# Explanation:
## Step1: Recall Dominance Rule
Purple (P) is dominant over white (p).
## Step2: Determine Phenotype for Each Genotype
- PP: Homozygous dominant → Purple
- Pp: Heterozygous (P is dominant) → Purple
- pp: Homozygous recessive → White
# Answer:
PP: Purple flowers
Pp: Purple flowers
pp: White flowers

### Question 3a
# Explanation:
## Step1: Recall Dominance Rule
Tall (T) is dominant over short (t). Tall phenotype includes homozygous dominant (TT) and heterozygous (Tt); short is only homozygous recessive (tt).
## Step2: List Possible Genotypes
- Tall: TT, Tt (has at least one T)
- Short: tt (only tt)
# Answer:
Tall = TT, Tt
Short = tt

### Question 3b
# Explanation:
## Step1: Recall Dominance Rule
Smooth (S) is dominant over wrinkled (s). Smooth phenotype includes SS and Ss; wrinkled is ss.
## Step2: List Possible Genotypes
- Smooth: SS, Ss (has at least one S)
- Wrinkled: ss (only ss)
# Answer:
Smooth = SS, Ss
Wrinkled = ss

### Question 4
# Explanation:
## Step1: Identify Parental Genotypes
Homozygous dominant (purple): PP; homozygous recessive (white): pp.
## Step2: Create Punnett Square
|   | P | P |
|---|---|---|
| p | Pp | Pp |
| p | Pp | Pp |
All offspring are Pp (heterozygous), which have purple flowers (since P is dominant). Thus, 0% have white flowers.
# Answer:
0% of offspring will have white flowers.

### Question 5
# Explanation:
## Step1: Identify Offspring Genotypes from Q4
Offspring from Q4 are all Pp (heterozygous purple).
## Step2: Create Punnett Square for Pp × Pp
|   | P | p |
|---|---|---|
| P | PP | Pp |
| p | Pp | pp |
Genotypes: 1 PP, 2 Pp, 1 pp. Phenotypes: PP (purple), Pp (purple), pp (white). Purple = 3/4 = 75%.
# Answer:
75% of offspring will have purple flowers.
