Present the data as monohybrids (Xx, XX, xx) for all five corn cobs andfor the plant. Present the colour and texture phenotypes with their associatedgenotypes in separate tables. Your first table should include the corn ID, the number of purple kernels, thenumber of yellow kernels, and the phenotypic ratio between the two kernelcolours. Present the texture results in the same format to a separate table.2. What is the dominant phenotype for kernel colour in your assigned cornplant? What is the dominant phenotype for kernel texture in your assigned cornplant?3. What are the probable phenotypes for the previous generation of cornplants with regard to kernel coloration?4. What are the probable phenotypes of the previous generation of cornplants with…

Figure 7.2 If a mutation occurs so that a fungus is no longer able to produce a minus mating type, will it still be able to reproduce? Figure 7.2 (a) In animals, sexually reproducing adults form haploid gametes from diploid germ cells. (b) Fungi, such as black bread mold (Rhizopus nigricans), have haploid-dominant life cycles. (c) Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism.

If homozygous recessive (aa,tetrapter) f1 produces homozygous (aa) f2, what is the dominant and recessive trait of f2? Let’s say the dominant trait of the parents of f1 is Wild type and the recessive trait is Tetrapter.
Doesn't the The F1 offspring being all LlDd means that the F1 centipedes have long legs and DARK colored bodies. Since D (dark) is dominant to to d (light)? Then if you drew a punnett swuare, wouldn't all the offspring being LlDd mean that none of the offspring have light bodies and short legs? So I don't understand the 25/4 fraction that you got for part a and where did the 1/16 come from?
