You have to start with low power, move to medium and then go to high. You have to be careful and use fine focus to make sure you don’t scratch the slide or the lens

Frank has Klinefelter syndrome (47, XXY). His mother has normal skin, but his father has anhidrotic ectodermal dysplasia, an X-l
Gala2k [10]

Answer:

b. Frank received the mutant chromosome from his father. Nondisjunction occurred in his father during the first meiotic division.

Explanation:

As you can see in the question above, Frank has Klinefelter syndrome which causes him to have normal skin patches and skin patches without sweat glands. Her mother has completely normal hair, which may indicate that the defective gene was not supplied by her. In addition, Frank's father has anhydrotic ectodermal dysplasia, an X-linked condition where the skin does not contain sweat glands.

Although Frank's father's defective gene is linked to the X chromosome, it is likely that Frank inherited the defective gene from his country. This may have occurred because during meiosis I, his father's genes did not show disjunction. As a result, Frank presents a mosaic of his phenotype, because an inactivation of the X chromosome occurred.

A mouse had a gene sequence of GTT coding for leucine, an amino acid. mutation in this gene led to the formation of GTG. However
Sergeu [11.5K]

Answer:

1- substitution.

2- neutral.

Explanation:

The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.

A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.

Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.
