A true breeding white flower with round petals is crossed with a true brreding yelow flower with pointed petals in f1 all of the have yellow flowers with round petals if the plants in the first generation self fertilize how many in the next generation will have yellow flowers with round petals if the genes segregate independently
In the F1 generation, all of the flowers have yellow flowers with round petals. This indicates that the round petal trait is dominant over the pointed petal trait.
If the genes segregate independently, we can use the Punnett square to determine the possible genotypes in the F1 generation:
White flower with round petals (RR): R R
Yellow flower with pointed petals (rr): r r
When crossed, the heterozygous offspring would have the genotype Rr.
When self-fertilized, the possible genotypes in the F2 generation would be:
RR (white with round petals) : R R
Rr (yellow with round petals) : R r
Rr (yellow with round petals) : R r
rr (yellow with pointed petals) : r r
Therefore, 2 out of 4 plants in the F2 generation should have yellow flowers with round petals, if the genes segregate independently.
