Question

Which of the following directly turn genes on or off? apoptosis growth factors transcription factors growth inhibitors ln the ABO blood group system in humans, if a person of type-B blood has children with a person of type-AB blood, what blood types could their children have? Please be advised that this is an example of non-Mendelian Inheritance. Type-AB, type-A, and type-B Type-A and type-B Type-B and type-A8 Type-AB, type-A. type*B. and type-0 A trait that is autosomal-dominant will be expressed even if only one copy of the disease allele is present in an individual. Based on the pedigree chart describing the inheritance of an autosomal-dominant disease, what is the probability that person A will birth an affected child if she mates with a wild-type male.

Explanation / Answer

(12) c.transcription factors

Transcription factors may bind directly to special “promoter” regions of DNA, and affect the gene expression

(13) a.Type-AB, type A, and type B

Explanation:

Type B person genotype= BB or BO

Type AB person genotype= AB

Probable children are = AB, BB, AO, BO
