You must draw a Punnett square and work out these problems to get the correct answers. In cats, long-hair (H) is dominant to sho
Lana71 [14]

Answer:

The correct answer is -

Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

Explanation:

It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.

Cross: Hh × hh

    H    h

h    Hh   hh

h   Hh   hh

In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.

So, Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

I need help with this (#20)
tester [92]

Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.
