Question

in a parent pea plant with the allele pair Gg, what is the probability they one gamete will contain the G allele?

Answer 1

If the pea plant is self fertilized, both gametes will have the same genotype Gg. Do a Punnett square and the G allele shows in three of four possibilities for each offspring, so the probability P = 3/4 or 0.75.

Answer 2

0.5
By la of segregation gamates will get different allele
Probability will be either G or g.
Thus it will 0.5
i.e. 50% will contain G
