Final Answer:
An allodiploid refers to an organism that has one set of chromosomes from two different species. This term denotes a hybrid organism resulting from the fusion of gametes from distinct species, creating a unique genetic combination. The answer is c. one set of chromosomes from two different species.
Step-by-step explanation:
An allodiploid refers to an organism that has two sets of chromosomes from two different species. This term is derived from "allo," meaning different, and "diploid," indicating the presence of two sets of chromosomes.
Allodiploidy results from the fusion of gametes from distinct species, leading to a hybrid organism with a unique combination of genetic material.
Unlike autopolyploids, which arise from within a single species, allodiploids possess chromosomes derived from two distinct parental species. This genetic divergence can have significant implications for the organism's traits, adaptability, and reproductive success.
Allodiploids highlight the potential for genetic variation and the dynamic nature of hybridization events in the evolutionary processes of certain organisms.
