How does the number of genes found on a human genome compare to the number of genes on the genome of a fish or mouse?
Humans have around 20,000-25,000 genes in their genome, similar to that of a mouse. Fish species may have varying numbers of genes in their genome, but generally have a comparable number to humans and mice. There is significant overlap in the number of genes found in human, fish, and mouse genomes.
What is hairpin tail deletion mouse experiment?
Targeting experiments in mouse have demonstrated that the majority of genes are in which has a dominant effect on tail length and is deleted in Thp.
Can cutting of the tails of mice for 100 generations result in a strain of mice with genes for short tails?
The length of the mouse tails are determined by their genes. If a mouse has a 6cm tail, then cutting the tail off will not affect the mouse's genes, you've only modified the mouse on a cosmetic level, not a genetic one. That mouse's genes still contain the 'blueprints' for that 6cm tail, and it is these it will pass on to offspring. It doesn't matter how many generations you do it for, you cannot change their genetic makeup like this. What you need to do is use artificial selection. Because of how genes work, there is variation amongst a species. These traits are what are passed on to offspring. You could take the mice with the shortest tails, and breed them together, then from their offspring, again breed the shortest tails together, and disallow the longer tailed ones from breeding. Eventually the average tail length of that group will become smaller, as more mice are passing on 'small tail' genes.
Where inside a cell did the mistake occur that caused some mouse like animals to get long fingers?
genes
A white mouse whose parents are both produces only brown offspring when mated with a brown mouse The white mouse is most probably what?
White fur color is recessive and brown is dominant. The white mouse has a genotype of bb and the brown mouse has a genotype of BB. All offspring would be heterozygous with a genotype of BB and brown fur.
In mice black hair B is dominant over white b the mouse with the genes BB would have what color hair?
The mouse with the genotype BB would have black hair because the dominant allele B controls for black hair color.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
How are most traits inherited the same way mouse fur color is?
Most traits are inherited through a combination of genes from both parents, following Mendelian inheritance patterns. This involves the passing down of specific alleles that determine the expression of a trait, similar to how mouse fur color is inherited from parent mice.
How do you know if a baby mouse is a mouse?
Is the mother a mouse? Is the father a mouse? Then yes, it is a mouse.
Would it be possible to splice animal genes with human genes?
any thing is possible, in 1995 they made a human like ear grow out of a mouse from cow tissue, and they have sheep that grow livers that are 25 percent human. so probably in the next 70 years if the people who have trouble with change dont stop it, but progress is impossible to stop.
Does prokaryotes have genes?
Of course they have genes. They need genes for survival and reproduction.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
