A scientist wants to ensure that a human zygote formed in a laboratory dish has the correct number of chromosomes. Number of chromosomes this zygote should have are:
46
A human zygote is formed by the fusion of a haploid egg (23 chromosomes) and a haploid sperm (23 chromosomes), restoring the diploid number.
23 + 23 = 46 chromosomes.
Hence, the correct answer is 46 (D).
