- Ronnie is convinced that baby Charlotte must be his daughter. He has heard about something called the “Bombay blood type”, and he is convinced that this phenomenon could explain how he could be Charlotte’s father. Please explain the Bombay blood type and its implications in this SPECIFIC situation, including (i) how it arises and (ii) genes involved, (iii) who would have the Bombay blood type in this scenario, and (iv) could Ronnie be Charlotte’s father, if this was present? Also (v) how could you determine whether the appropriate person actually had the Bombay blood type?
