After crossing purebred red (dominant) and purebred white (recessive) flowers, pink flowers appeared. Using symbols, show the cr
-Dominant- [34]
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

How does deforestation lead to helping conservation?
Nitella [24]

Answer:

Deforestation leads to the loss of biodiversity and of indigenous tribes’ homes. Deforestation also affects billions more people around the world indirectly, through its impact on climate change, water and nutrient cycling and food availability. The world’s benefit from conservation far outweighs the costs to the owner, such as the profit they lose by not logging. It would thus make sense for the wealthier North to simply pay the tropical countries in the South to conserve and protect their forests.
