1. a membrane-bound nucleus

2. numerous membrane - bound organelles including the endoplasmic reticulum, Golgi apparatus, chloroplasts and mitochondria.

3. several rod-shaped chromosomes.

Because a eukaryotic cell's nucleus is said to be surrounded by a membrane, it is said to have a true nucleus.  Organelles (meaning "little organ")  have specialized cellular roles just like the organs of  the body have specialized roles.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?
yuradex [85]

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.
