<h2>d) is the correct option </h2>
Explanation:
B= black coat color (dominant)
b= brown coat color (recessive)
S= striped fur pattern (dominant)
s= marbled fur pattern (recessive)
A cross is made between black striped cat(genotype unknown) and brown marbled cat (bbss genotype)
(here in this brown marbled cat is homozygous recessive)
Resulting offsprings are:
3 brown marbled= both coat and fur color recessive
2 brown striped= coat color recessive fur color dominant
2 black marbled= coat color dominant fur color recessive
3 black striped= both coat color and fur color dominant
Crossing brown marbled cat with the genotypes given in options, the correct genotype of rescued cat comes out to be: BbSs
