Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.

1. The pedigree below shows the incidence of rare, autosomal dominant disorder called Ehlers-Danlos disease.

There is a woman who is a carrier for hemophilia and marries a man with hemophilia. a) Complete the Punnett Square (it is a google drawing so you will have to double click it to go to the drawing and type in and around the square. Hold the CONTROL (or Command) button and press the PERIOD button to write a superscript/exponent.) b) What are the possible genotypes of the children? c) Could any of their children have hemophilia? If so, would the child be male or female? Explain your reasoning.

1. A) Apply the concept of sex linkage to explain why color blindness is more prevalent in men than in women. B) Mary is concerned that she may be a carrier for hemophilia, a sex-linked condition located on the X chromosome. Mary is married to John, who doesn't have hemophilia. Assuming Mary is a carrier, what are the genotype ratios expected for Mary and John's kids (specify for boys and for girls)? C) Mary and John have 2 boys, none of them has hemophilia. Can we use this fact as proof that Mary does not carry the allele for hemophilia? Explain your argument.

Using the pedigree chart, explain: a) The number of generations seen. b) If all blue-coloured shapes are affected with disease X- how many males are affected? how many females are affected? c) Does this disease have a dominant or recessive inheritance pattern? Justify your answer.
Using designations "Group A", “Group B," etc., organize the mutant strains into complementation groups. If the result of any cross does not fit your groupings, indicate which cross(es) you have excluded. Consider the consequence if one of the mutations was dominant. You should see that complementation tests could not be used to provide information about dominant mutations. a) If a mutation were dominant, how would the diploid be affected? What effect would this have on the determination of your complementation groups? b) How would you test if any of these trp¯ mutations were dominant?
