In another laboratory a short haired guinea pig is crossed with a long haired one and not a single offspring has long hair. Show the cross that explains the situation

See the answer below

Explanation:

11. For none of the offspring have had long hair, it means the long hair allele is recessive to the short hair allele. Let us assume the short hair allele to be A and the long hair allele to be a. The short hair guinea pig would be homzygous with AA genotype and the long hair would have aa genotype.

         AA    x    aa

      Aa    Aa    Aa    Aa

Due to the fact that A is dominant over a, all the offspring would have short hair. See the FIRST attached image for the Punnet's square analysis.

12. The second attached image shows the cross between homzygous curly hair guinea pigs (GG). All the offspring would be with curly hair. The percentage is, therefore, 100%.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
