Basically it is more complex then just one locus gene interaction, but basically if both parents have brown hair they can have a child with blonde hair because both parents could be heterozygous for brown and pass on the recessive allele for blonde hair. in simple genetic analysis this would happen to 25% of the children.

A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
Many trials are taken and averaged in an experiment to reduce the measurement error.
A great manner by which error is reduced or to enhance the accuracy of measurement is to take many measurements and compute their average. In other terms, one attain accuracy via averaging.
This also validates the repeatability of the measurement. The kinds of experimental error include mistakes in data entry, human error, mistakes in the design of the experiment, or systematic error, or random error due to environmental circumstances.
