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.

What is the difference between immune deficiency and opportunistic infection?
RoseWind [281]

Answer:

Immunodeficiency disorders prevent your body from fighting infections and diseases. This type of disorder makes it easier for you to catch viruses and bacterial infections. Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with.  whereas Opportunistic infections (OIs) are infections that occur more frequently and are more severe in people with weakened immune systems, including people with HIV. Many OIs are considered AIDS-defining conditions.

Amino acids are the monomers of proteins. Each amino acid consists of a carbon atom bound to a hydrogen atom, an amino group (-N
umka2103 [35]

In amino acids, the carboxyl group acts as an acid.

Answer: Option B

<u> Explanation: </u>

The molecular formula of the carboxyl group is -COOH. It is composed of one carbon atom bonded with oxygen atom and hydroxyl group.

During ionization process, it leads to the formation of two ions namely a positive ion called H^{+}, whereas a negative ion called COO^{-}. Due to the formation of H^{+} ions, which is nothing but a proton, the carboxyl group present in the amino acid act as an acid.
