a.
To determine: The results presented summarizing the main findings.
Introduction. Maternal effects are the resultant of the maternal genes that influence the
b.
To determine: The explanation for the results produced from a cross between Funaria hygrometrica and Funaria mediterranea.
Introduction. Multiple allelism is the condition where one character or trait is controlled by various alleles and not just the two alleles.
c.
To determine: The method for testing the explanation and how it can be distinguished from other explanations.
Introduction. The genotype of an organism is dependent on its genome and also on the environment of the organism. In some of the animals, it is not as typical as the genotype of the mother plays a crucial role. This type of effect is known as a maternal effect. The genes that participate in this are called maternal effect genes.

- The purple colour results from the formation of a purple pigment in the skin of the kernel. The gene locus for the colour trait is designated “R”. The wrinkled phenotype arises from a decrease in the amount starch produced within the kernel. The gene locus for the texture trait is designated “S”. Present the data as monohybrids (Xx, XX, xx) for all five corn cobs andfor the plant. Present the colour and texture phenotypes with their associated genotypes in separate tables. Your first table should include the corn ID, the number of purple kernels, the number of yellow kernels, and the phenotypic ratio between the two kernel colours.

The Bombay variety of flax is resistant toM. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flaxcalled 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1individuals were self-fertilized, the following data were obtained:43 resistant to strain 22 but sensitive to strain 24 Explain the inheritance pattern for flax resistance and sensitivityto M. lini strains.9 sensitive to strain 22 and strain 2432 sensitive to strain 22 but resistant to strain 24110 resistant to strain 22 and strain 24arrow_forward

And why would the other options wrongarrow_forwardI don't really understand how to solve this question. For part a, I think my approach would be to find the genotypes of the parents first, and find the genotype of the F1. For part B, I would like to get some clarifications on the difference between linked genes with no crossing over vs. unlinked genes when approaching Punnett square type questions.
