There are 50% chances  of a gamete receiving mother's chromosome.

<u>Explanation:</u>

In the process of reproduction, the male gamete (sperm) and female gamete (ovum) fuses to form a zygote. In humans, the zygote has 46 chromosomes out of which 23 chromosomes come from father and 23 chromosomes comes from mother. The contribution of the number of chromosomes from both mother and father is equal.

Thus, there are 50% chances of a gamete receiving mother's chromosome. However, we carry more of mother's genes than the father's because genes present in mitochondria is transferred only from our mother.

A gamete is randomly getting a copy of a chromosome from its mother and father. This means that gamete will get #1 from the mother and the next chromosome will be a pure chance of getting chromosome #2 from mother or father.

Explanation:

  • Meiosis is the process that separates the two chromosomes and giving one copy of each to the gamete. This is the reason why egg and sperm together are forming zygote which is diploid.
  • The main advantage of sexual reproduction is that each clone is different. Each and every egg is different from each other. This is the same in the case of sperm too.
  •  At the end of meiosis, males will have 1 cell with 4 sperms all are different in nature, but in females, it will one egg because, during cell division, one cell will hog the cytoplasm.
