Amouse had a gene sequence of gtt coding for leucine, an amino acid. (a. deletion b. an inversion c. a substitution) mutation in this gene led to the formation of gtg. however, the amino acid formed was leucine, despite the mutation. this is(a. beneficial b. harmful c. nuetraul.) a mutation for the mouse.

(its fill in the blank and abc is given multiple choice answers

1- substitution.

2- neutral.

Explanation:

Mutation is the change in the genetic sequence of the organisms that change might be sudden and heritable in nature. The two different types of mutation are spontaneous mutation and induced mutation.

The mutation that might result in the change in the single base pair of a gene sequence is known as substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. The last base pair T has been substituted by G.

Mutation can be beneficial, detrimental or neutral for the humans. The neutral mutation do not affect the humans. Before mutation the gene codes for leucine and even after mutation the gene codes for the same amino acids and hence can be considered as neutral mutation.

Thus, the answer is 1- substitution.

2- neutral.

the correct answer would be d. hope this !
