- 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.arrow_forwardUse the following information to answer the next question.

Be very specific in describing your experimental design and how you would interpret your results based on the proportion of offspring phenotypes.

Some Traits in Garden Pea Plants In pea plants, the genes for seed shape, seed colour, and plant height demonstrate independent assortment. The alleles for these genes are symbolized as follows: R (round) >r (wrinkled) Y (yellow) > y (green) Answer: Seed shape Seed colour - Plant height T (tall) > t (short) What percentage of the gametes produced by a pea plant heterozygous for both seed shape and seed colour would be expected to contain both the allele for wrinkled and the allele for green? (Record your answer as a whole number. Do not include the percentage sign)arrow_forward
- You identify a gene that determines the size of the pods of a pea plant. To study the phenotype associated with this trait, you cross a plant that is homozygous for the “long pod” allele with a pea plant that is homozygote for “short pod” allele. When measuring the length of the pods of the parents and resulting offspring, you obtain the following data: Plant Length (cm) Homozygous (“Wide” allele) 15 cm Homozygous (“Short” allele) 4 cm Resulting cross breed 9 cm What can you conclude about this phenotype/trait? Long and short alleles are codominant Wide allele shows incomplete dominance over the short allele Wide allele shows complete dominance over the short allele Short allele shows complete dominance over the long allele The wide and short genes are linkedarrow_forwardPea plants were a good model organism for Mendel because A -they had large flowers and were easy to manipulate b -there were many contrasting traits c -both a and b d- none of the abovearrow_forwardWhat is the role of chance and direction in determining the phenotype of an organismarrow_forward
