Text is frequently incorporated into comics via speech balloons, captions, and sound effects. Speech balloons indicate dialogue (or thought, in the case of thought balloons), with tails pointing at their respective speakers. Captions can give voice to a narrator, convey characters' dialogue or thoughts, or indicate place or time. Speech balloons themselves are strongly associated with comics, such that the addition of one to an image is sufficient to turn the image into comics. Sound effects mimic non-vocal sounds textually using onomatopoeia sound-words.
What association with comics is strong?

London i/ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south eastern part of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms Greater London,[note 1] a region of England governed by the Mayor of London and the London Assembly.[note 2] The conurbation also covers two English counties: the small district of the City of London and the county of Greater London. The latter constitutes the vast majority of London, though historically it was split between Middlesex (a now abolished county), Essex, Surrey, Kent and Hertfordshire.

According to Mendelian inheritance, variations in an organism's phenotype (observable physical and behavioral characteristics) are due in part to variations in its genotype (particular set of genes). Each gene specifies a particular trait with different sequence of a gene (alleles) giving rise to different phenotypes. Most eukaryotic organisms (such as the pea plants Mendel worked on) have two alleles for each trait, one inherited from each parent.:20

According to Mendelian inheritance, what is part of the cause of variations in an organism's phenotype?
