Final answer:
Offspring get traits from two parents through the process of heredity in sexual reproduction. This type of reproduction combines genetic material from both parents, leading to genetically unique offspring, unlike asexual reproduction, which involves only one parent and results in genetically identical offspring.
Step-by-step explanation:
The mode of reproduction where an offspring receives traits from two parents through the process of heredity is Sexual reproduction. During sexual reproduction, genetic material from two different parents combines to form a new organism, resulting in genetically unique offspring. This is because the male and female sex cells, or gametes (sperm and egg), fuse together during fertilization to create a zygote, which then develops into an embryo.
In contrast, asexual reproduction involves a single parent and produces offspring that are genetically identical to the parent. This can occur through various mechanisms such as binary fission, budding, and fragmentation, all of which do not involve the mixing of genetic materials from two different individuals. Parthenogenesis, another form of reproduction, can lead to diverse offspring but typically involves only one parent as well.
