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 pink to white flowers.

How many covalent bonds would you expect a neutral carbon atom to form in an organic compound?
hoa [83]
The number of covalent bond an element can form depends on the number of electrons it has in its outermost shell (valence electrons). Carbon has four valence electrons, therefore, it can form maximum of four covalent bonds in an organic compound.
