To study the relative rate of recombination in zebrafish (Danio rerio), Singer et al. (2002) constructed a genetic map based on male meiosis from androgenetic haploid embryos.

Electron micrographs of zebrafish meiosis. (a) Zygotene oocyte, showing 50 stretches of SC with an attachement plaque at one of each.(b) Pachytene oocyte with 24 completely paired bivalents and ...

There have been two types of cell division that we've known about for a long time, and they have been studied extensively. Organisms that reproduce sexually have a certain population of cells called ...

baz1b loss-of-function in zebrafish produces phenotypic alterations consistent with the domestication syndrome. iScience , 2023; 26 (1): 105704 DOI: 10.1016/j.isci.2022.105704 Cite This Page : ...

If a zebrafish’ spine is injured, the damaged neurons respond by dramatically changing their cellular functions. They take on a new and central role in orchestrating the very precise events that ...

Zebrafish use surprising strategy to regrow spinal cord Detailed blueprint of nerve cells' dramatic changes could help identify ways to heal spinal cord damage Date: August 15, 2024 ...

Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, ...

How Cells Divide: Mitosis vs. Meiosis by Rick Groleau As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced.

Zebrafish are only a few centimeters long, but they’ve got some supersized powers. When their hearts or brains are damaged, they regenerate. When their fins are cut off, they grow back.

They discovered that the protein Hmga1 plays a key role in heart regeneration in zebrafish. In mice, this protein was able to restore the heart by activating dormant repair genes without causing ...
