Question

Potatoes are a very important vegetable crop in the US and many farmers and consumers rely on them. Because of the increase in temperature caused by climate change, many crops, including potatoes, are suffering because they can't tolerate the high temperatures. 1. What biological trait(s) are needed to solve this problem and in what organism(s) would you find a gene for this trait? 2. Describe the entire process of how to make your new GMO 3. What are the potential health issues or environmental impacts of your new GMO? Remember that you must cite at least 1 peer-reviewed source for full credit. A genetic counselor is evaluating a family's risk for an autosomal genetic disease and is reviewing the family pedigree and results from a diagnostic screen done using gel electrophoresis. Legend Luis Affected male Unaffected male Affected female Unaffected female Lorena Oscar Diego

Explanation / Answer

1. GENOTYPES OF FAMILY MEMBERS :

Colour blindness.

carrier of allele of this disease.

affected with any disease.

2. Yes, Disease allele is homozygous recessive. Since, In pedigree chart Luis is affected male parent and Erica

is disease carrier( itself not affected but transfer allele to next generation) give three young ones. In those

ones Lorena is affected because it has genotype XcXc ( in this genotype first Xc is comes from Luis & second

from Erica). Oscar & Diego unaffected male(XY) because both have not any affected allele from there  

parents.

CONCLUSION: It is homogygous X-linked disease because it shows its effect when its allele is present on both the sex chromosomes. If it would a dominant allele disease then all three children should be affected.

3. If Diego marries phenotypically normal wife. In this case two conditions are arise :

(a) Since Diego is phenotypically as well genotypically healthy and its wife is phenotypically healthy but if it is

a disease carrier (XCX OR XXC) then 50% sons would be affected and 50% daughters would be disease

carrier and the remaining 50% son and daughters would be completely healthy.

(b) But, Wife is phenotypically as well as genotypically healthy then all the children would be born free from

this disease.
