The reason due to which the calico cats are always considered as female. Introduction: The cats which have patches of both white, black and orange fur are called calico cats. Calico cats do not follow the rules of Mendelian genetics . Mendelian genetics does not allow the expression of different genes at one time. According to Mendelian genetics, cats can only have white, orange, or black fur. The fur color in cats is controlled by different genes.

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.

Two albino poodles met at a dog park and fell in love. The two dogs decided to be exclusive and not see any other dogs. One day the female poodle became pregnant; shortly after six beautiful puppies were born. However, much to the shock of the towns folks, they were all dark brown! Not that it's anyone else's business, for goodness sake, but did a handsome brown poodle catch the eye of our lady here? Or did she stay true to her one love? O She had to have an affair! It would be impossible for two albino dogs to have dark brown puppies, since albinism is a recessive trait. O It is possible for to two albino dogs to have non-albino offspring as long as there is more than one gene required for pigmentation.

Calico cats are almost invariably female. Why? (Hint: explain genotype and phenotype of calico females)

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses? a.Environment mismatch hypothesis b.Endocrine disruptor hypothesis c.Thrifty genotype hypothesis d.Plasticity first hypothesis
