Question

How are seedless oranges produced in other countries?

A) By cross-breeding with other fruit varieties
B) By removing seeds through a special process
C) By natural mutation
D) By using genetic engineering techniques

Answer 1

Seedless oranges in other countries are produced through a process called parthenocarpy, which is the production of fruits without seed development. This can occur spontaneously through mutations or can be intentionally developed through breeding programs.

Step-by-step explanation:

Seedless oranges in other countries are produced through a process called parthenocarpy, which is the production of fruits without seed development. This can occur spontaneously through mutations or can be intentionally developed through breeding programs. For example, seedless watermelons are triploid plants bred by crossing a tetraploid plant with a diploid plant. In some cases, seedless varieties still require pollination but the seeds soon abort. Seedless oranges are not produced through cross-breeding, removing seeds, or genetic engineering techniques.
