(http://)1. What is the phenotype of the female and what is the phenotype of the male with respect to the three traits shown in the above diagram?
   Hint: Two possible ways to help visualize the traits is to write the genotypes as
      The female is deP; the male Dep
                   deP             dEP
      The female as ddeePP; the male as DdEdPp

2. A genetic counsellor told the couple that all their sons and daughters would be expected to produce peptidase C. Do you agree with the genetic counsellor? Explain.

3. The first child of this couple was Rh-negative. What is the chance that the second child of this couple be a girl and be Rh-negative? Show your work
   Hint: 0.50 is incorrect(http://[img])[/img]

4. Nomenclature for writing alleles on a homologous chromosome pair The phrase DEP/dep means the first three letters, DEP, represents the alleles that will appear, in this order, on the first homeless chromosome. the "/" signifies the following alleles, deep, will appear on the second homologous chromosome.  It is to be assumed that the genes will appear at the same location on both the two homologous chromosomes.

A student wrote the male genotype as DEP/dep. Do you agree? Explain.
   Hint: Distance from the centromere and map units apart from other genes are factors in _______.
      Correct: the probability of crossing over

5. The sperm chromosome maps are more likely to be DeP than DEP. Explain
   Hint: Again the location of the alleles on the chromosome is important. The farther apart, and the greater the distance from the centromere, the higher the crossover rate.

Can anyone help with number 1 above?
I am so completely lost

does anyone know this answer

Thank you
