Answer:
Mother - XAXA
Father - XY
Explanation:
Please see the attached image - complete question
Solution -
In the second cross the female is affected while the male is unaffected
The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.
Let the allele representing a diseased X gene be XA
and the allele for normal X gene be X
The offspring have all diseased males, which means that the genotype of affected female will be XAXA
And the genotype of unaffected male will be XY
Answer:
Food borne intoxication
Explanation:
Foodborne diseases occur when we consume food which is contaminated with a pathogenic microbe or toxins released by these microbes. Foodborne diseases can be classified into foodborne infection and foodborne intoxication.
Foodborne infection occurs when we consume food contaminated with pathogenic organisms and foodborne intoxication occurs when we consume food which contains toxins or poisonous substances released by the pathogenic microbes.
Botulism is a foodborne intoxication caused by ingestion of toxins produced by C. botulinum. So the correct answer is foodborne intoxication.
