Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabil
Zanzabum

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.

How does weathering shape earths surface
balu736 [363]

Answer: Weathering constantly changes the earth's surface by wearing away exposed surfaces, smoothing rough areas of rocks and causing rock materials to break down in time. Weathering creates soil and happens due to ice, wind, water, salt, acids and changes in temperature Gravity shapes the Earth's surface by moving weathered material from a higher place to a lower one.
