Solution
The correct option is C Xenia
- The term “Xenia” was originally coined to refer direct effect of pollens on seed and fruit characters or effect of gene from male parent on development of fruit and seed.
- However, as of now, it is restricted to denote effect of pollen grains on endosperms. For example- the colour of endosperm in Maize is determined by pollens.
- Effect of pollen genes on fruit shape and fruit characters is known as metaxenia
Thus, the correct answer is option C.
