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)
