Statistically, there is a 50/50 chance that a
specific trait expressed in a seedling comes from either parent. However,
dominance and recessiveness play a significant role in the determination of
trait expression. If the female is comprised of mostly dominant alleles,
and the male is comprised of mostly recessive alleles, then the female traits
will be expressed. Another point to consider is that the genetic
codes for mitochondria and chloroplasts (energy producers and sunlight
harvesters) are ALWAYS maternally inherited. This may play a significant
role in pumpkin size. (I can explain more on this as per your
request.)
Incase you did not understand any of that
jibber jabber, here's the simplified version. All
seeds receive 50% of their genes from their mom, and 50% from their
dad. Most seeds display a
mix of characteristics from both parents.
Hope this helps!
