The roles fulfilled by the males increase the survival of the species is males scare off predators and protect the pack.
<h3>What does fittest animals mean?</h3>
According to natural selection, there is a constant struggle for survival and only the fittest organisms are selected. These fitter organisms would be able to pass on their advantageous traits to their descendants.
Generally the main factors that cause the destruction of a habitat are deforestation, fires, livestock, agriculture and human occupation. Don't stop now.

There will be no recombinant progeny in absolute linkage. The F1 inherted banded and yellow alleles (BBCY) together on one chromosome from the banded yellow parent and unbanded and brown allels (BOCBw) together on the homologous chromosome from the unbanded parent. All the F1 gametes will contain only these two allelic combinations, in equal proportions if there is no recombination. F2 cross progeny will have 1/2 banded, that is yellow and 1/2 unbanded brown.
        
             
        
        
        
When humans farm large plantation of one cash crop, they reduce the biodiversity of the region because they reduce the genetic diversity of the species in the environment. A reduction in genetic diversity means that the genetic variability of the species is reduced  hence there are fewer sub-species in the environment. This ultimately reduces the biodiversity of the ecosystem -  which is the variability among all the living organisms in the environment.
