Consider the ABO “blood type” gene. This single gene has three alleles called A, B, and O. There are four resultant “blood types” (phenotypic classes), as follows: C
                         
Assume Hardy-Weinberg equilibrium,  the frequencies of the A and B alleles are 0.26 and 0.07, respectively. You now examine the ABO blood types in a new population. You observe that the A, B, and O blood types all have equal frequencies in this population. What are the frequencies of the A and O alleles in this population?

#Unit 8. Inheritance Biology

  1. Frequency of allele A = 0.5470                                       Frequency of allele O = 0.2265

  2. Frequency of allele A = 0.2265                  
    Frequency of allele O = 0.5470
  3. Frequency of allele A = 0.365                    

    Frequency of allele O = 0.9480

  4. Frequency of allele A = 0.3379                  
    Frequency of allele O = 0.5470

1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA,

2. Their large size makes the handling procedures during cloning tedious and cumbersome

3. A general lack of unique cloning sites within the T-DNA, which are needed for the insertion of DNA segments to be cloned.

These three problems have been resolved by deleting

The use of wild type pTi as a vector presents the following three problems.
1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA, which causes a disorganised growth and a loss of regeneration potentiaLof the cells having T-DNA in their genomes.
2. Their large size makes the handling procedures during cloning tedious and cumbersome.
3. A general lack of unique cloning sites within the T-DNA, which are needed for the insertion of DNA segments to be cloned
