Sure, let's break this down step by step:
1. Identify Parent Genotypes:
- One parent is homozygous dominant for purple flowers, which we denote as [tex]\( FF \)[/tex].
- The other parent is homozygous recessive for white flowers, which we denote as [tex]\( ff \)[/tex].
2. Determine Possible Gametes:
- The homozygous dominant parent [tex]\( FF \)[/tex] can only produce gametes with the [tex]\( F \)[/tex] allele.
- The homozygous recessive parent [tex]\( ff \)[/tex] can only produce gametes with the [tex]\( f \)[/tex] allele.
3. Cross the Gametes:
- Each offspring will receive one allele from each parent.
- The only possible combination of alleles from these parents is [tex]\( F \)[/tex] from the homozygous dominant parent and [tex]\( f \)[/tex] from the homozygous recessive parent, forming the genotype [tex]\( Ff \)[/tex].
4. Determine Phenotype:
- In pea plants, the allele [tex]\( F \)[/tex] for purple flowers is dominant over the allele [tex]\( f \)[/tex] for white flowers.
- Therefore, the genotype [tex]\( Ff \)[/tex] will result in the dominant phenotype, which is purple flowers.
5. Calculate the Percentage of Offspring with Purple Flowers:
- Since all offspring [tex]\( (100\%) \)[/tex] will have the genotype [tex]\( Ff \)[/tex], all will exhibit the dominant phenotype (purple flowers).
Hence, the percentage of the offspring that will have purple flowers is:
A. [tex]$100\%$[/tex]
