In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?

Biology

yuradex [85]2 years ago
7 0

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype  tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

What is ischemia? Coronary infraction?
Alex17521 [72]

<u>What is ischemia?</u>

It can affect your heart, your intestines, and any part of your body. If this happens it can end up triggering a sequence that leads to your death.

<u>Ischemia is.. </u>

an inadequate supply of oxygenated blood to all or part of a tissue or organ as a result of an obstructed or constricted blood vessel.

<u>Not sure what you mean by "Coronary infraction?", but</u>

The word "infarction" comes from the Latin "infarcire" meaning "to plug up or cram."

A salamander relies on hydrogen bonding to stick to various surfaces. therefore, a salamander would have the greatest difficulty
Talja [164]

The hydrocarbons' surface.

Because the covalent link that exists between hydrocarbon surfaces is different from the surfaces to which the salamander can cling, the salamander has difficulties adhering to these surfaces.

The hydrogen bond is the bond that exists between hydrogen and a bigger molecule like nitrogen or oxygen, whereas a covalent bond includes sharing electrons.

<h3>What Are Hydrocarbons and What Do They Do?</h3>

Crude oil, natural gas, and coal are all examples of hydrocarbons, which are organic compounds made of hydrogen and carbon. The world's primary energy source and a highly flammable substance, hydrocarbons. Petrol, jet fuel, propane, kerosene, and diesel are only a few of its uses.

Name the five cardiac cycle activities starting with excitation and ending with regulation of blood flow and volume.
stira [4]

Answer:

Explanation:

1) Excitation brings about contraction.

2) Contraction leads to an increase in blood pressure.

3) Changes in blood pressure results in the opening and closing of the heart valves.

4) The opening and closing of heart valves then regulates the flow of blood and it's volume.

huntington disease is a dominant disease caused by expansion of the trinucleotide repeat region of the htt gene that results in
Travka [436]

By haphazardly introducing a transgene harboring a disease-causing mutant variant of the HTT gene into the genome of a mouse or primate, it is possible to produce an animal model with the majority of the symptoms of this condition. Here option B is the correct answer.

Huntington's disease is an uncommon, genetic condition that results in the gradual degeneration of brain nerve cells. Huntington's illness, which frequently results in mobility, cognitive, and psychological problems, has a substantial impact on a person's functional capacities.

A DNA region known as a CAG trinucleotide repeat is involved in the HTT mutation that causes Huntington's disease. Three DNA-building building pieces that are repeated several times in a row make up this region.

Complete question:

Huntington's disease is a dominant disease caused by the expansion of the trinucleotide repeat region of the Htt gene that results in the production of a Huntingtin protein with an expanded number of glutamines. An animal model with most features of this syndrome could be created by

A - knocking in a wild-type copy of the Htt gene to a mouse or primate genome.

B - randomly inserting a transgene containing a wild-type allele of the Htt gene to a mouse or primate genome.

C - randomly inserting a transgene containing a disease-causing mutant allele of the Htt gene into a mouse or primate genome

D - knocking out one copy of the wild-type Htt gene from a mouse or primate genome.

E - knocking out both copies of the wild-type Htt gene from a mouse or primate genome.
