The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion. **Gene, Allele, Locus, and Enzyme**The image presents a detailed explanation of how gene variations, specifically alleles, impact the synthesis of enzymes and the resulting flower color. Here are the key elements:1. **Chromosomes and Alleles:** - Two chromosomes are displayed, each with different alleles for flower color. - The locus for the flower-color gene is marked, showing where the alleles are located on the chromosomes. - One allele is for purple flowers and the other for white flowers.2. **DNA Sequences and Enzymes:** - The top chromosome has DNA with the nucleotide sequence "CTAAATCGGT", while the bottom has "ATAAATCGGT". - The sequence with "C" leads to the production of an enzyme crucial for synthesizing purple pigment. - The enzyme is depicted as a 3D structure, indicating its role in this biochemical pathway.3. **Outcome of Enzyme Production:** - The presence of the enzyme synthesized due to the "C" sequence results in purple flowers, as shown by an illustration of a purple flower. - The absence of this enzyme in the "A" allele results in no color pigment, leading to white flowers.This diagram effectively connects the genetic coding on homologous chromosomes to the physical traits observed in organisms through enzyme activity.

Gene It is a part of DNA that contains information for specific character or trait. Gene code for proteins which affect things like hair colour, skin pigmentation, eye colour, etc. Allele In simple we can say the multiple form of a single gene. When a gene get mutated, it sequence changes. Now this new form of gene still code for same trait but the appearance will be different, for example hair colour. Ans. The phenotype of flower in homozygous recessive condition is white. In homozygous condition, both gene are same and code for same enzyme which produce same effect for example in this case flower colour. When the pea plant gene is in recessive condition for flower colour then the phenotype of flower is white. On both the chromosomes, the allele present on the loci which give flower colour in pea plant is white. The gene which give white colour produce no enzyme. In the absence of enzyme which give pigmentation to the flower, there will be no pigmentation and in the result the colour of flower will be white.Conclusion Recessive gene present at both the loci --- gene code for unable to code for enzyme -- as result no pigmentation -- the colour of flower is white.
