1. possible gamete genotypes produced by an individual of genotype ppdd are
a) pp and dd
b) all ppdd
c) pd and pd
d) pd, pd, pd, and pd

D) PD, Pd, pD, and pd

Explanation:

You need to draw a Punnet chart and put P (represent a dominant character) and p (represent a recesive character) abobe. Then D (represent a dominant character diferent than P) and d (represent a recesive character different tan d).

When you do the cross over, you will end with four possibles gamete genotypes and those are PD, Pd, pD and pd.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
