Answer:
The two blue budgies are most likely to be yyBb each
Explanation:
there are 3 different scenarios possible for crossing blue budgies:
1) yyBB crossed with yyBB
this is not possible because it does not allow for the genotype yybb (white budgies)
2) yyBB crossed with yyBb
again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement
3) yyBb crossed with yyBb
which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring

Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
