Answer:
d. 1/3
Explanation:
Given, M is a dominant allele which is responsible for tailless kittens and m is recessive wild type allele which leads to kittens with tail. M is a lethal allele which means that if it is present in homozygous condition, the kitten will not survive. So the Manx cats should be heterozygous i.e. Mm.
When they mate, Mm X Mm :
M m
M MM Mm
m Mm mm
1/4 kittens will have MM genotype so they will not survive. Out of the remaining kittens, 1/3 will be mm and hence they will have normal tail. Remaining 2/3 will have Mm genotype like their parents and will be born without tail. Hence, there is 1/3 probability that one of the four kittens will have a normal tail.
Answer:
decomposers are essential as they break down the dead organic matter and return the nutrients back to soil which they had taken earlier for their survival and they clear the ground leaving no waste and enrich the soil by nutrients.

Reliable; it has been proven to be right in multiple tests, therefore it is a solid data
