- Mention the advantages of selecting pea plant for experiment by Mendel.arrow_forwardUse the following information about pea plants: S = spherical seeds; s = wrinkled seeds Y = yellow seeds; y = green seeds P = purple flowers; p = white flowers I = inflated pods; i = constricted pods Write the possible genotypes for the following conditions: Heterozygous for spherical seeds Homozygous for wrinkled seeds Homozygous for spherical seeds and heterozygous for flower colorarrow_forwardShow seven parts of constarsting traits in pea plant studied by mendal?arrow_forward
- 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_forwardUsing Mendel’s lines of peas, describe how you would use a test cross experimental design to determine the genotype of a pea plant with purple flowers. Be very specific in describing your experimental design and how you would interpret your results based on the proportion of offspring phenotypes. Make sure to include all possible offspring phenotypes in your answer and what the proportion of phenotypes tells you about the purple plant genotype.arrow_forward
- specify how genetic principles are used in plant breeding.arrow_forwardConsider 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. Find all the ways that the heights of the grandparents average to exactly 50 cm.arrow_forward
- A type of fast plant strain that can be used to study genetics is yellow green leaf in which the homozygous recessive plant will have pale yellow-green leaves. Predict the F1 generation phenotype of a cross between a dwarf rosette plant and a pale yellow green plant. short and green short and yellow-green tall and yellow-green tall and greenarrow_forwardWhy was Mendel’s success dependent on his studying characteristics that exhibit only two easily distinguished phenotypes, such as white versus gray seed coats and round versus wrinkled seeds? Would he have been less successful if he had instead studied traits such as seed weight or leaf length, which vary much more in their phenotype?arrow_forwardThe results of a test cross of a plant that is heterozygous for three traits encoded by the genes D, R, and Q are summarized in the table (below), which shows the numbers of offspring that inherited each combination of alleles from the heterozygous parent. Use the data collected to make a genetic map of genes D, R, and Q. Make a map of the distance between these three genes. Report your results by entering the genetic distance between each pair of genes to the nearest 0.1 cM in the blanks below.
