Can somebody me with #s 4, 5, 6 and 7? i need to make punnett squares.

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)

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
