Answer:
Explanation:
Since the offsprings all exhibited purple phenotypic characteristics, It shows that in the gene coding for colour in the flower of the pea plant, the allele for purple colour is dominant over the allele for white colour.
It further shows, according to the law segregation, that the gametes produced by the purple and white peas are dominant and recessive respectively. This Indicates that the parent purple-flowered pea is homozygous dominant (PP) while the parent white-flowered pea is homozygous recessive (pp), hence all the offsprings will be heterozygous dominant (Pp).
Answer:
Diffusion
Explanation:
As substances like oxygen are non polar and are not dissolved in water they can diffuse through the cell membrane without the need of channel proteins whereas polar molecules would be repelled by the hydrophobic tails of the phospholipid bilayer an would need a channel protein
