ABO blood grouping of humans is an example of co-dominance. Homozygotes (1^1^ and 1816) express either the A or the B
phenotype. Heterozygotes (1415) express both pheno
the result of the genotype 1940: this blood type is considered the recessive trait and I° is the recessive allele for blood type.
Consider the genetic cross for blood type of these two parents. The father is type A and the mother is type B. Both have the
recessive allele for blood type 0. Wh
offspring with type A blood?

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
