Question

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 PH has a child with a woman with the finn genotype, what is the probability that their first child will also have type blood B? Show your work for full credit

Answer 1

no VOSS L group 3 Answer:- = Bombay blood group (genotype hh) or Oh = phenotype is rare autosomal recessive phenotype. - Bombay blood phenotype in human results in - blood type ŏ because of the lack of both the A and B antigens in individuals who are of hh aerotype . - The genotype results in blood type o regardless = of the genotype at the unlinked I locus - Here the man is with the genotype 1A 10 HhAblood S and " woman » " no Alb nn To blood] = 1110 According to punoret square] L E ALAALA " B blood group in child will . . occur when the genotype for - 1B 1A 18/1910 I locus will be 18, and genotype for H locus will be Hh / 1320 1 H h = 1 x 1 -nHh hh = { Hn [belona) Hence, the probability that the first child will shave B blood genotype = 1:1 group is 1/3 o punnet square AN = gewlype = 1:1:1:1 n thun
