The very rare Bombay blood phenotype in humans results in blood type o because of the lack of both the A and B antigens in individuals who are of hh genotype. This genotype results in blood type o regardless of the genotype at the unlinked /locus. If a man with the genotype º Hh has a child with a woman with the hh genotype, what is the probability that their first child will also have type blood B? Show your...

GENETICS* Bombay phenotype problem
3) (2 pts) A man with type B blood and a woman with type O blood produce a male child with type AB blood. a) Provide a genetic explanation that includes the genotypes for each of the three individuals. b) If the male child above mated with a female with the same blood type (AB) and the same genotype, what is the probability of producing a child with O blood type? What about A blood type?
Question 47 of 50 4.0 Points The bicold mutant is recessive, and the Bicold gene is a maternal effect gene that leads to proper development of the head region in fllos. Two flies that are heterozygous for the blooid mutant are crossed. What are the chances that the first progeny will have normal head development Show your work for full credit. Describe why a gene would have a maternal effect phenotype. (Hint where is the protein or mRNA of a...
There are three main alleles in the ABO blood group system -
IA, IB, and i. We've talked about the ABO
system in class, you can find a brief explanation below and
here.
The I gene encodes for a glycosyltransferase
that modifies at the H antigen.
The glycosyltransferase encoded by IA adds an 'A'
sugar group to antigen H, the glycosyltransferase encoded by
IB adds a 'B' sugar group and i encodes an inactive
glycosyltransferase that leaves the H antigen...

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...
1. In humans the allele for A type (IA) blood and B type blood (IB)show co-dominance, so that a person with both alleles has blood type AB (phenotype). Both A and B alleles are dominate to the allele for O (i). A person with an allele for type A blood and an allele for type o blood marries someone with an allele for type B blood and an allele for type o blood. List the types of offspring they could have and...
