|
An embryo’s cells differentiate to perform specialized functions.

Detailed explanation-1: -The correct answer is-In sexual reproduction, the offspring of a human being is not a true copy of its parents because it inherits half of its genetic material from each parent. During the formation of gametes (sperm and egg cells), the genetic material undergoes a process of recombination known as crossing over.
Detailed explanation-2: -The DNA copying mechanism is not absolutely accurate, and the resultant errors are a source of variations in organisms. Hence the offspring produced are not clones.
Detailed explanation-3: -The statement is false. The daughter cells produced by asexual reproduction are similar to their parent. In contrast, sexual reproduction produces a similar but genetically different offspring. In the process of sexual reproduction, haploid gametes produced by the meiotic division fuses to form a diploid zygote.
Detailed explanation-4: -Sexual reproduction is the process in which two parents are involved which produce two types of gamete i.e., male and female. The gametes fuse to form the zygote during fertilization. This is a compulsory event which allows the continuation of the species.
Detailed explanation-5: -Expert-Verified Answer OF THE FOLLOWING A) GAMETES ARE NOT INVOLVED IN ASEXUAL REPRODUCTION.
