Since after crossing a red and a white flower produced pink flowers, the red color trait shows an incomplete dominance and has a genotype of Rr.
Using the Punnett to determine the cross between pink and white flowers:
| R | r |
r | Rr | rr |
r | Rr | rr |
The results indicate that the cross between pink and white flowers will produce a ratio of 1:1
Rr x rr
There are both natural and human sources of carbondioxide<span> emissions. Natural sources include decomposition, ocean release and </span>respiration<span>. Human sources come from activities like cement production, </span>deforestation<span> as well as the burning of </span>fossil fuels<span> like </span>coal, oil<span> and </span>natural gas<span>.</span>
