What else can I help you with?
A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (White is the recessive color)?
A pretty bow
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.
A brown mouse is repeatedly mated with a white mouse all the offspring are brown if two of the offspring are mated what fraction of the F2 mice will be brown?
75% or 3/4. The two F1 (offspring) mice have a genotype Bb, and express the dominant (brown) trait. When they mate, 1/4 will be BB (homozygous dominant - brown), 2/4 will be Bb (heterozygous - brown), and 1/4 will be bb (homozygous recessive - white).
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.
What are dominant and recessive alleles with examples?
dominant alleles will always overrule recessive alleles. So if you have any dominant allele in the phnotype or geneotype, the dominant trait will be expressed. For example, since black fur is dominant to brown fur on mice, if two black mice mate, at least part of their offspring will have black fur. If they are heterozygous for black, though, that's when a brown mouse offspring may be possible, but there would always be more black offspring than brown offspring. parents offspring (4) Bb x Bb --> BB, Bb, Bb, bb BB x Bb --> BB, BB, Bb, Bb BB x BB --> BB, BB, BB, BB BB x bb --> Bb, Bb, Bb, Bb Bb x bb --> Bb, Bb, bb, bb anything with a capital B would be black while "bb" is the only brown.
What is the length of a mouse and not a computer mouse?
Mice are typically under 2 inches long with a tail of similar length. Rats however are much bigger than mice.
What is the genotype of a white mouse?
The probable genotype for the white mouse would be homozygous recessive.
Is a mouses tail longer then its body?
While there is no precise length for a mouse, the typical person thinking of mice will likely be thinking of the house mouse (mus musculus). The length of an adult house mouse from nose to base of tail is 7.5-10cm (3-3.9in) with a tail length of 5-10cm (2-3.9in).
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.
Suppose you have two mice one black one white the genotype for the black mouse is WW and the genotype for the white mouse is ww What would the punnet square look like?
It would look like this. --¦ W W -------------- w¦ Ww Ww w¦ Ww Ww All the offspring would be black-furred, all carrying one dominant gene and one recessive.
Which metric would scientist use to measure the length of a mouse's tail?
Mm
What might happen if mouse color was not passed from parent to offspring?
The parent had a recessive gene or a gene with incomplete dominance. The rare case of albinism may also be the cause.
