Question
In sexual reproduction ______ gametes fuse to form _________ zygote.
Diploid, haploid
Diploid, diploid
Haploid, diploid
Haploid, haploid
Diploid, haploid
Diploid, diploid
Haploid, diploid
Haploid, haploid
Hint:
Child receives 50% of chromosomes from each parent.
The correct answer is: Haploid, diploid
Living organisms are made up of two types of cells:
- Somatic or body cells
- Sex cells or gametes
Somatic cells have two sets of chromosomes and are called diploid (2n).
Gametes contain only one set of chromosome and are called haploid (n).
During fertilization, the haploid (n) cells (egg or sperm) fuse together to form a diploid zygote (2n). Thus, a child receives 50% of chromosomes from each parent.
- Cells are classified into somatic and gametes
- Somatic cells are diploid
- Gametes are haploid
- Haploid gametes fuse together to form diploid zygote
