The answer is C) Increase genetic variation and breed plants to contain the wild variety.
A,B,C,D I'm pretty sure, but check with others who answer the question too.
Ans.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.

Ears
¿Qué es el oído y qué hace?
El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.
El oído externo
El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.
El oído medio
El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.
Explanation:
Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells.
Meiosis is the type of cell division for the production of gametes in sexual reproduction . Meiosis is the process through which egg and sperm cells are formed. Mitosis is a necessary step for life.
A cell copies all of its components, including its chromosomes, and separates to generate two identical daughter cells during mitosis.
Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Mitosis is the division of a single cell into two identical daughter cells (cell division).
Mitosis is a kind of cell division that occurs in somatic cells as well as in unicellular eukaryotic cells during asexual reproduction. Meiosis is a sort of cell division that occurs during sexual reproduction to produce gametes.
