How many chromosomes does zebrafish have?
25 chromosomes
The haploid zebrafish genome has 25 chromosomes, most of which are difficult to distinguish. These chromosomes contain about 1.7 X l09 base pairs of DNA, about half the mammalian genome size.
How long is the zebrafish genome?
The total length of the zebrafish mitochondrial genome was 16,596 bp, within 100 bp of the length of other teleost fishes. It is particularly close to two other cyprinid fishes, only 18 bp longer than the goldfish (Carassius auratus) and 21 bp longer than the carp (Cyprinus carpio).
How many genes are in Danio rerio?
We describe the complete sequence of the 16,596-nucleotide mitochondrial genome of the zebrafish (Danio rerio); contained are 13 protein genes, 22 tRNAs, 2 rRNAs, and a noncoding control region.
What is the scientific name of zebrafish?
Danio rerio
Zebrafish/Scientific names
Since the 1960s, the zebrafish (Danio rerio) has become increasingly important to scientific research. It has many characteristics that make it a valuable model for studying human genetics and disease.
How do zebra fish lay eggs?
Zebrafish lay eggs which are fertilized by the male after they are laid. Your fish is probably full of eggs and waiting for a male (usually skinnier and slightly yellow on the bottom side) to mate with. She won’t lay the eggs without a male.
How old do zebrafish have to be to breed?
Although zebrafish reach sexual maturity in 10-12 weeks, the breeding fish should be between 7 and 18 months of age for maximum embryo production. Keep males and females in separate tanks with up to 8 females or 16 males per 10 gallon tank. The tanks should be cleaned at least once per day by siphoning,…
Is there a 5th edition of the zebrafish book?
This material is from the 4th edition of The Zebrafish Book. The 5th edition is available in print and within the ZFIN Protocol Wiki. This method requires more work, but is especially well suited for production of large numbers of embryos (upwards of 1000 embryos per tank) once or twice a week.
How often do you have to feed zebrafish?
Keep males and females in separate tanks with up to 8 females or 16 males per 10 gallon tank. The tanks should be cleaned at least once per day by siphoning, replacing about 1/3 of the water. Feed the fish 2-3 times per day.
