Dark-colored mice from two different populations living hundreds of miles apart were examined and the mice looked nearly identical. The dark color fur in the two different populations of mice was caused by two different genes. What does
this tell you? (Note: More than one answer is correct.)
Dark color fur evolved only once in rock pocket mice
Under similar conditions, natural selection can favor similar adaptations
Different mutations in two different genes cannot generate the same phenotype
There are at least two genes involved in creating dark-colored mouse fur
Dark fur color evolved independently on each lava flow

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.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
