Ans.
A monohybrid cross can be defined as 'a cross between two individuals having different copies of a chromosome or gene of interest, which is responsible for variations in a single trait.'
These variations in a single trait are controlled by two or more alleles for a single chromosomes. For example, a cross between tall pea plant and dwarf pea plant to study the inheritance of plant height.
Thus, the correct answer is 'option). they differ in a single trait.'
Carbon Monoxide has 2 atoms total - one atom of carbon (C) and one atom of oxygen (O) chemical formula is CO
Ethylene has 6 atoms total, 2 atoms of carbon (C) and 4 atoms of hydrogen (H), chemical formula is C2H4.
Ethylene has four more atoms than carbon monoxide (6-2) = 4
That would be an ionic bond. Which is an attraction between a cation and an anion.
