That's the correct term in terms of biology or any science field. Basically, they are all connected with each other, so it makes it look like it's a web.
Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
Answer:
B or Letter B
Explanation:
Ovules are found in the ovary. The ovary can be described as the oval structure at the base of the flower.
The flower is found in the Angiosperms, that is, the flowering plants. And it is known to be the part of the plant that allow sexual reproduction to occur. The flower usually contains the reproductive parts, which include
* Androecium... This is known to be the male reproductive part of a flower, and it comprises the Anthar { this encloses the pollen grains}, and the filament.
* Gymnoecium... This is the female part of the flower and comprises of the stima, style and the ovary { encloses the ovules}.
In conclusion, the pollen grains will fuse with the ovules,[ this is known as fertilization], to form a fruit. The pollen grains can be compared to the spermatozoa in Man, while the ovules are like eggs in the woman.
