in african-violet plants,purple flowers are dominate to white flowers. You purchase an African- violet plant with white flowers. It's genotype could be represented as:
PP ORGANISMS WITH RECESSIVE TRAITS MUST BE HOMOZYGOUS RECESSIVE (2 lowercase letters)
Trait colour of plant parental phenotype; purple and white parental genotype; Pp and Pp
To determine the genotype of an African-violet plant with white flowers, let's use the following notation:
- Dominant trait (purple flowers): represented by the letter P
- Recessive trait (white flowers): represented by the letter p
Since the purple flowers are dominant over white flowers in African-violet plants, the genotype for a plant with white flowers can be represented as pp. In this case, both alleles are recessive, resulting in the expression of the recessive trait (white flowers).
To determine the genotype of an African violet plant with white flowers, we need to consider the laws of inheritance. In this case, we know that purple flowers are dominant over white flowers.
Genotypes are represented by pairs of alleles, where the dominant allele is typically represented by an uppercase letter and the recessive allele by a lowercase letter. In this case, let's represent the white flower allele as "w" (recessive) and the purple flower allele as "W" (dominant).
So, if a plant with white flowers has a white flower allele from both of its parents, its genotype would be "ww". This means that it carries two recessive alleles for white flowers.
However, it's important to note that there could be other genes involved in determining the flower color of African violets. This simplified explanation assumes that flower color is controlled by a single gene with two alleles.
If you'd like a more precise understanding of the genotype, a genetic test or breeding experiment would be necessary to determine the specific alleles involved.
