You are trying to determine the linkage map of a series of genes, x, y, and z, from caenorhabditis elegans, a nematode worm commonly used in scientific research. from doing several crossover experiments, you know that the recombination frequency between x and y is 11.5%, between y and z is 13%, and between x and z is 25%. what is a possible sequence of these genes?

X-Y-Z

Explanation:

Recombination frequency is the frequency of cross over that takes place between two genes during meiosis. Genes which are linked lie close to each other hence they do not assort independently and tend to get inherited together. Closer the genes, more is this tendency and lesser is the recombination frequency.

Here, genes X and Z show the highest recombination frequency i.e. they are the farthest. Gene Y shows intermediate recombination frequency with both the genes ( 11.5% with gene X and 13% with gene Z ) so it must lie between them. Hence, the possible sequence of these genes is X-Y-Z.

the answer would be knowledge about cars!

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
