Question

If each one of the parents has single mutated gene, the probability of their children not to have any mutated gene is 1 out of4 2 out of 4 3 out of 4 4 out of 4 18. If each one of the parents has a single mutated gene, the probability of their children to have 1 mutated gene is 1 out of4 2 out of 4 3 out of 4 4 out of 4 18. The gene responsible for cystic fibrosis has around 189,000 base pairs but the protein it produces has only about 1, 500 amino acids. How many bases are actually used to code the protein? 1,000 3,000 1, 500 4, 500 It is more probable for females to suffer from muscular dystrophy than males True False. Males and females have the same probability of suffering from this disease False. It is the other w ay around because males with just one mutant gene will suffer from it, but females require two mutant genes to suffer from this disease False. It depends if the mutated gene comes from the father or from the mother Identify the false statement Rennet coagulates milk and is found in the lining of a calf s stomach Most hard cheese in the United States is produced with rennet Bacteria can be genetically modified to produce chymosin Chymosin is the active milk coagulating enzyme in rennet.

Explanation / Answer

16:- option a 1 out of 4

Exp:- out of 4 children one would be with no mutated gene whereas rest three contain mutated gene .

17:- option b 2 out of 4

Exp:- the probability of having one mutated gene would be 2 out of 4.

19:- option C

Exp:- False. It is other way round for muscular dystrophy to occur minimum two mutated alleles must occur in females because the gene responsible for it is present on X chromosome but in males having single X chr. single mutation is enough to cause muscular dystrophy
