we learned not only about the importance of Mendel's Laws (segregation and independent assortment) to heredity, but also that there are a number of exceptions to Mendel's Laws. Inheritance follows some basic ideas, but can certainly appear to be a tricky thing if you don't fully understand the basis of how the traits of living things come about. This discussion, therefore, will focus on the exceptions to Mendel's Laws so that it will help you better understand how traits come about. You should look up more information on an exception and provide us with a better understanding of it in your postings. Different examples, importance, effects on traits including diseases, and other things can certainly be addressed. Please let me know if you have any questions on this interesting and relevant topic. I need 2 outside sources with IN-Paragraph citation as well as an ending citation. Use your words.. We also use https://openstax.org/details/concepts-biology

In the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, behavior and DNA, genetic evidence suggests that the living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered species status should be withdrawn because the remaining red wolves are hybrids, not members of a “pure” species. Do you agree? Why or why not? Support your stance with examples.

You are a researcher who is interested in three genes in drosophila: The a gene, the b gene and the c gene. You think the genes may be linked, so you decide to do a cross using a true-breeding a+/b+/c+ fly and an a/b/c fly. The F1 generation is all a+/b+/c+. However, when the F1 generation is bred to a true-breeding a/b/c fly, it yields the following offspring phenotypes: 596 a+/b+/c+ ; 589 a/b/c ; 183 a+/b/c ; 176 a/b+/c+ ; 0 a/b+/c ; 0 a+/b/c+ ; 0 a+/b+/c ; 0 a/b/c+. Which What is a possible interpretation of your results?

Group of answer choices

The b and c genes demonstrate 100% (complete) linkage.

The b and c genes are recessive lethal alleles.

The a gene is a dominant lethal allele.

The a and b genes demonstrate 100% (complete) linkage.
