Summary Introduction

To review:

The difference between recessive, X-linked, and dominant patterns of inheritance in accordance with the Pedigree analysis.

Introduction:

Pedigree analysis is the method used to determine the inheritance of genetic disorders. It is an important tool for studying the inherited disorders in the generations. The pedigree chart helps to visualize the relations between the large extended families.

Explanation of Solution

Differentiation between X-linked, dominant, and recessivepatterns of inheritance, according to the pedigree analysis are shown below:

Recessive inheritance X-linked inheritance Dominant inheritance
Affected offspring has unaffected parents. Both, parents and offspring are affected. Unaffected offspring have affected parents.
It is associated with autosomal genes. Based on the X-chromosome genes. It associated with the gene on the autosome.
Recessive traits affect females and males equally. Traits skip generations to appear and males are more affected than females. Females are the main carriers of the disease. Dominant traits affect both male and female offspring in each generation. Dominant X-linked is always passed on from father to daughter.
Conclusion

Therefore, it can be concluded thatX linked disease affects males, while in dominant inheritance, the disease affects the daughter. In recessive inheritance, both, the males and females have an equal chance of disease inheritance.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
