Just for fun, imagine that “shirt-striping” is a phenotypic character caused by a single gene. Construct a genetic explanation for the appearance of the family in the above photograph, consistent with their “shirt phenotypes.” Include in your answer the presumed allele combinations for “shirt-striping” in each family member.

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…

Locus A has two alleles (A and a) while locus B has two alleles (B and b). The recombination frequency between locus A and locus B is 17%.  A F1 heterozygote in trans-configuration is mated with an aabb individual. What are the expected phenotypic percentages in the resulting progeny? Round your percentages to the nearest tenths and in the following format, replacing the "0.0" with your percentages:

How do you figure out the geno and phenotype from the info given? 2 pages out the lab but I figured once explained I’ll be able to do understand and do the rest!

When Mendel did his experiments, it was the case that the genes for each trait were on separate pairs of homologous chromosomes. For example, the genes for pod color were on one pair of chromosomes and the genes for the seed coat were on a different pair of chromosomes. What if the genes for the two traits were on the same chromosome? (That is, if the gene for pod color was on the same chromosome as the gene for seed coat.) Would Mendel’s 2nd Law still hold? Why or why not?

Cystic fibrosis (CF) is an autosomal recessive trait. A three-generation pedigree is shown below for a family that carries the mutant allele for cystic fibrosis. Note that carriers are not colored in to allow you to figure out their genotypes.      Normal allele =  F      CF mutant allele =  f        What is the genotype of individual #13? A) ff B) FF C) Ff  D) it is impossible to tell

It has been hypothesized that people who are heterozygous for the allele that causes the deadly genetic condition cystic fibrosis (which, among other symptoms, reduces fertility) are more resistant to the deadly disease tuberculosis.   Question - if the cystic fibrosis allel protects against tuberculosis the same what the sickle cell allele protects against malaria, then which of the following should be true in comparison between regions with or with out TB. -cystic fibrosis deaths should be more common in regions with tb - CYSTIic fibrosis deaths should be less common in regions with tb -  CYSTIic fibrosis deaths should be equally common in regions with tb -Regional differences in the cystic fibrosis death rate should be purly random and upredictable.

This pedigree (below) shows inheritance of a genetic disorder in a family. Assume the trait is rare. What is the mode of inheritance for this trait? [Select] You know this because that mode of inheritance is characterized by: [ Select] • An affected male parent passes the allele to [Select] and [Select] individuals who have the allele express it and and [Select] of his daughters. • An affected female parent passes the allele to [Select] of her daughters. ㅇㅁㅇㅁ î то ◆ of his sons of her so ?

Joseph is heterozygous for the traits F (dominant to f) and B (dominant to b)and his genes are in cis, and these locuses are on the same chromosome and separated by 30 map units. Sara is also heterozygous for these traits but here genes are in trans. Calculate how likely it would be to observe an individual who is homozygous dominant for the genes F and B. Be sure to show your work for full credit.

In the world of Weeping angels, those with pointy wings are (A_), while those with round wings are (aa). In the efforts to explore this extraordinary species, you wish to determine the genotype of a pointy winged angel. Luckily, you have trapped a round winged angel that you can cross your pointy winged angel with. If the pointy winged angel is homozygous what phenotypic ratio do you expect from their offspring? (Pointy wing: round wing) Group of answer choices a. 1:0 b. 2:1 c. 1:1 d. 3:1
