Introduction:
Genetics is the study of the transmission of characters from the parental generation to offsprings. It revolves around the DNA molecules which store all the genetic information essential for an organism to grow, survive, and reproduce.

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.
The continuity of life is based on heritable information in the form of DNA. Use the law of segregation and the law of independent assortment to explain how the passage of genes from parents to offspring (as alleles) ensures the perpetuation of parental traits in offspring and genetic variation among offspring. Describe briefly how Mendel demonstrated each of these laws.
Make a figure (or figures) showing a pair of homologous chromosomes. Show genes/alleles that are linked and those that are unlinked. Which genes/alleles are likely to be inherited together? Explain and be sure to include crossing over events in your explanation. Consider giving traits to your genes/alleles to aid in your explanation.

- Imagine you cross two closely related plant varieties: Maize and teosinte. You hypothesize that different alleles at just 5 genes are responsible for all the trait differences between the two plants. You take two inbred parent lines and cross them together to produce an F1 and then cross two F1 individuals together to produce F2 offspring. What proportion of the offspring do you expect to look exactly like each of the parent lines if your hypothesis is correct? Please show work using punnet squares.arrow_forwardTo analyze: According to the given information, wild-type allele of a gene has an A-T base pair at a particular location in its sequence, and a mutant allele of the same gene has a G-C base pair at the same location. Apart from this change, the sequences of the two alleles are same. Based on above information, a question is asked as whether this information tells us anything about the dominance relationship of the allele. If yes, we need to explain why. If no, we need to explain why not.arrow_forwardMendel describes subjecting each of the 34 varieties of peas he obtained to a two-year trial.
