Most gourds that I am familiar with are from a different genus - Lagenaria. In that case they will not cross with each other. Some decorative gourds are in the genus Cucurbita and will cross. The result may then not be very edible if the gourd dominates. You will get a mixture. If they are edible, it would be when the fruit are very small.
As spaghetti squash is a Cucurbita pepo and a banana squash is a Cucurbita maxima, they will not cross. Only cucurbits within the same species will cross-pollinate so you can grow one of each. Incidentally, the fruit of crossed species is still edible, but often inferior.
The right answer is "cross" or "cross pollination" or "cross-pollination"
It is known as pollination (sometimes as cross-pollination).
The purpose of cross-pollination and self-pollination are to perform reproduction so off spring can be produced.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
cross and self pollination
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
Cross pollination or cross fertilisation.
You can create a hybrid between two species through their cross pollination, but that is not new species.
To create more genetic variability so as give momentum to the process of evolution.
There are 2 types of pollination 1. Self pollination. 2. Cross pollination.
