The passage describes part of the process of reproduction in mice. Complete the passage by writing a suitable word in each blank space. The male mouse produces gametes called __________ that swim to the female gamete. Each gamete has the haploid number of chromosomes, which is 20 in mice. The gametes join in a process called __________. The single cell produced is called a __________ and contains the __________ number of chromosomes. This cell divides by __________ into an embryo. Each cell in the embryo contains __________ chromosomes.
Understand the Problem
The question is asking to complete a passage about the reproductive process in mice by filling in blanks with suitable words.
Answer
The male mouse produces gametes called sperm that swim to the female gamete. Each gamete has the haploid number of chromosomes, which is 20 in mice. The gametes join in a process called fertilization. The single cell produced is called a zygote and contains the diploid number of chromosomes. This cell divides by mitosis into an embryo. Each cell in the embryo contains 40 chromosomes.

More Information
In mice, as with other mammals, reproduction involves the formation of gametes which have haploid chromosomes that combine through fertilization to create a zygote. This zygote, with the full diploid chromosome number, undergoes mitosis to become an embryo.
Tips
A common mistake is to confuse the haploid and diploid number of chromosomes. Remember, haploid cells have half the number of chromosomes compared to diploid cells.
