Inheritance patterns cannot always be explained by Mendel's models of inheritance. If a pair of homologous chromosomes fails to
soldier1979 [14.2K]

The question is incomplete as it does not have the options which are:

A) n+1; n+1; n-1; n-1

B) n+1; n-1; n; n

C) n+1; n-1; n-1; n-1

D) n+1; n+1; n; n

Answer:

Option-1

Explanation:

The laws of inheritance were concluded from the result of Mendel's experiment which is based on the fact that gametes are formed. Later research suggested that gametes are formed by the process of meiosis which takes place in two phases and recombination is a characteristic of Meiosis.

If during anaphase I of meiosis I, the alleles fails to separate that is nondisjunction takes place at anaphase I, Then the resulting daughter cells will have unequal distribution of chromosomes.

One daughter cell will receive 1 extra copy of the chromosome while another daughter cell will receive 1 less chromosome therefore ploidy level will be n+1 and n-1.

During meiosis II, 2 more daughter cells will be formed with the same ploidy level therefore in last the meiosis will result in 2 (n+1) and 2 (n-1) cell.

Thus, Option-1 is the correct answer.

AURORKA [14]

Answer:

Part A....B

Part B....C

Explanation:

It should be understood that Mice are always first used to clinical test especially for drugs or other things that are supposed to be for human use, this is because Mice and human genetic disorders have arisen from conserved and related evolutionary processes. Therefore, when the clinical trial or test produces a positive result in the Mice, it is almost certain that the result will be the same in human.

Now in part B. When the result result is different, it might be because of the differences in anatomy and physiology might hide or change development and symptoms of disease. And that is the reason why, the result of a particular drug differs from person to person.
