A)

It is possible to obseve that the fur color of the feline is connected with the male chromosome "X". The presence of Xb (recessive) and XB (dominant) results in the tortoise color.

The ausent tail T is carried in the autosomes with a dominacy over the presence of tail "t" and the presence of both dominances "TT" results in the death of the offspring.

B) Genotypes of the parents:

Male: XbY, Tt

Female: XBXb, Tt

In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.

It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.
