RFLPs can be used to follow the can be used to regions. Under the are near a defective gene determine whether present in an unborn has you second died shortly after birth from an inherited genetic disease, and tha mother pregnant again Their first affected a brother of the paternal grandmother of the child was in to be lo the other, The couple withes know has disease You the region, in and know that it is caused by an utosomal The the has several restriction-site polymorphismo within the population as a whole, as indioa6nd restriction A.The site is present. restriction site n the population are designation restriction to correctly is absent). that you understand this figure in order answer the question. You isolate DNA samples from both parents, both sets of grandparents, and the unaffected child that are dark mean that there aro more o intensities light and dark that are in There are only two band emember that each of us has an autosomal chromosome from our mother and an a we chromosome from our father so at any one locus one may be homozygous or hotorozygous What restriction pattern (combination of bands) will indicate to you that the fetus is likely to be have inherited and will likely be affoctod by the disease? (A) RESTRICTION MAP (B) GENEALOGYExplanation / Answer
Answer:B
presence of the band 2,6 and 9
Restriction Fragment Length Polymorphism is a difference in homologous DNA sequences that can be detected by the presence of fragments of different lengths after digestion of the DNA samples in question with specific restriction endonucleases.
