If an egg cell contains 50 chromosomes, how many chromosomes are in a sperm cell from the same species? 50 25 100 200

The number of chromosomes is 50.

The fusion of male gamete and female gamete leads to the formation zygote. The chromosome number of both the male gamete and female gamete remains same. The male type of gamete is sperm whereas the female type of gamete is ovum. The gametes are haploid in condition.  

The term haploid refers to the quantity of chromosomes in egg or sperm cells, which contain equal number of chromosome. Thus, from the given data, it can be inferred that if egg has 50 chromosome, then the sperm will also have same 50 chromosome.
