You are studying a newly discovered gene, whose alleles code for one of two phenotypes, either achondroplasia (a form of dwarfism) or average stature. Please describe how you could use a cross to assess which of the two conditions is genetically dominant over the other. Use Punnett squares, as appropriate . You may include a picture or a table THAT YOU HAVE MADE to represent your Punnett square(s).

The allele for albinism ( c ) is recessive to the allele for normal pigmentation ( C ). A normally pigmented woman whose father is an albino marries an albino man whose parents are normal. They have three children, two normal and one albino. Give the genotypes for EACH person listed.

Part of the difficulty of the genetics unit is knowing what type of problem you are being asked to solve and then solving it correctly. The following problems are a mix of normal Mendelian inheritance, incomplete dominance, co-dominance, sex-linked, and dihybrid crosses. Complete each of the problems below. Show your work! It’s difficult for me to know where you are making your mistakes (and help you to correct them) if I cannot see how you completed the problem. in certain fish, the mating of a black (B) fish with a white (W) fish will create offspring with a patchwork of black and white scales. What type of inheritance pattern is this?_____________________________________________ If a black and white fish is crossed with a black fish, what percentage of the fish will be: Black? ___________% White? ____________% Black and white? ___________%

You are trying to find a blood donor to help treat some of your patients. The C-yonce and Kay-Z have 3 children with blood types A , B, and O. The youngest with blood type O needs a transfusion and you're trying to figure out if either of the parents are a match so you test the parent genotypes. Note: Alleles for each blood type are expressed as follows: blood type A= I^A blood type B= I^B blood type O= i Hint: Remember that 2 alleles contribute to a persons blood type. Pay attention to dominant and recessive relationships among the alleles.     1-C-yonce is type B. What must her genotype be? 2-What must Kay-Z’s genotype be? 3-Which parent can give blood to their child ? 4-After running lab tests, it was discovered that the children's blood types were reported incorrectly.(This does not affect the genotypes entered for C-yonce and Kay-Z in the previous questions.) Their youngest actually has blood type AB, and still needs a blood transfusion.  Which parent can donate blood to the child…
