Did you know?
WebThus, in plants the gametes are formed by mitosis not meiosis, which fuse to form a zygote and then a sporophyte. Meiosis is a special type of cell division which is found in sexually reproducing organisms. The process decreases the number of chromosomes by half in gametes in compared to parent cells which in return enable sexual combination. WebQuestion. Cells at the end of meiosis (i.e. each of the four gametes) have _____ when compared with cells at the. beginning of meiosis (i.e. the parent cell in prophase I). a. half the number of chromosomes and one-fourth the amount of DNA. b. half the number of chromosomes and half the amount of DNA. c. the same number of chromosomes and …
WebGametes or sex cells are reproductive cells. These are haploid cells wherein each of them carries one copy of the chromosome. Usually, a mature haploid male and female gamete … WebWe can confirm the link between the four types of gametes and the 9:3:3:1 9: 3: 3: 1 ratio using the Punnett square above. To make the square, we first put the four equally probable gamete types along each axis. Then, we join gametes on the axes in the boxes of the chart, representing fertilization events.

WebPlants show alternation of generation between a gametophytic and a sporophytic body. The gametophytic body can be either male or female. These are haploid structures which produce gametes. The gametes fuse to form a zygote and give rise to a diploid sporophytic body. Let us look at their differences:
