So, one at a time: I'm attaching a picture of the punnet squares (hard to make on the computer (and you can simplify the ratios down):

4. HHnn x hhNN

All offspring are HhNn; 100% same genotype (HhNn); 100% phenotype of short, normal

5. HhNn x HhNn

Genotypes and ratio:

HHNN(1): HHNn(2): HhNN(2):HhNn(4):HHnn(1):Hhnn(2): hhNN(1):hhNn(2):hhnn(1)

Phenotypes and ratio:

Short normal (9): short colorpoint(3):Long normal (3): Long colorpoint (1)

6. TtNn x ttnn

Genotypes and ratio:

TtNn(4):Ttnn(4):ttNn(4):ttnn(4) (which is 1:1:1:1)

Phenotypes and ratio:

Tabby normal (1): Tabby colorpoint (1): Stripless normal (1): stripless colorpoint (1)

7. hhNn x hhNn

hhNN(4): hhNn(8):hhnn(4)

short normal (12): short colorpoint (4)

1. Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.

2. </span>Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3. Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. </span>Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.

5. </span><span>A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent. 
Parents:          Yy      x     yy
Offspring:    Yy    Yy    yy   yy
50 % is Yy  and 50% is yy.

7. </span><span>One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents:       Rr     x     rr
Offspring   Rr    Rr   Rr   Rr

8. </span><span>Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

10. <span>Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents:        Pp     x     Pp
Offspring:   PP   Pp   Pp   pp
One of the four is white.</span>
