- Describe three advantages of using pea plants as an experimentalorganismarrow_forwardThe 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.arrow_forwardspecify how genetic principles are used in plant breeding.arrow_forward
- Consider the following hypothetical gene a plant. Gene T produces a protein that impacts stem length. There are two alleles for geneT, T which produces long stem and t which results in short stem if gene T displays incomplete dominance and what of the following genetype above would have a different phenotypearrow_forwardConsider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents.
