a.
To determine:
The genotype of the parental type sperm John could produce in the given cross.
Introduction:
The set of genes in our DNA that is responsible for a certain trait is termed as the genotype. If the two organisms have even the slightest difference, their gene will have different genotypes.
b.
To determine:
The genotype of the recombinant type sperm produced by John.
Introduction:
The genetic makeup of an organism is termed as the genotype. It describes a complete set of genes of an organism.
c.
To determine:
Whether the B and D loci are linked or assort independently.
Introduction:
According to Gregor Mendel’s law of independent assortment, when two or more traits are inherited, the alleles for separate traits are transmitted to the next generation independent of each other. The assortment of one allele does not affect the selection of the other trait. When two genes are linked, they tend to be inherited together. When two genes are located on the same chromosome or occur very close to each other are said to be linked.

- What did the Cre-lox system used in the Kikuchi et al. 2010 heart regeneration experiment allow researchers to investigate? What was the purpose of the cmlc2 promoter? What is CreER and why was it used in this experiment? If constitutively active Cre was driven by the cmlc2 promoter, rather than an inducible CreER system, what color would you expect new cardiomyocytes in the regenerated area to be no matter what? Why?arrow_forwardWhat kind of organ size regulation is occurring when you graft multiple organs into a mouse and the graft weight stays the same?arrow_forwardWhat is the concept "calories consumed must equal calories burned" in regrads to nutrition?arrow_forward
- You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?arrow_forwardDescribe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo.
