Question
Q3Pink flowers are obtained from a cross between pure breed red flower plant and pure white flower plant. What is the genotype of the pink flower?1 markRRRWWWRrQ4A pink flower is crossed with another pink flower. The genotype of pink flower is RW. How many percent of offspring is pure white?1 mark0%25%50%100%Q5Based from the problem in no. 3, how many percent of offspring is pink?1 mark0%25%50%100%
Solution
Q3: The genotype of the pink flower is Rr. This is because the red flower plant (RR) and the white flower plant (WW) cross to produce the pink flower plant (Rr).
Q4: The percentage of offspring that is pure white is 25%. This is because when a pink flower (RW) is crossed with another pink flower (RW), the possible genotypes are RR (red), RW (pink), WR (pink), and WW (white). Therefore, there is a 1 in 4 chance, or 25%, that the offspring will be pure white (WW).
Q5: The percentage of offspring that is pink is 50%. This is because when a pink flower (RW) is crossed with another pink flower (RW), the possible genotypes are RR (red), RW (pink), WR (pink), and WW (white). Therefore, there is a 2 in 4 chance, or 50%, that the offspring will be pink (RW or WR).
