Check the answers below:
• Genetic Drift refers to the change of the frequencies of allele due to some random events• All the choices are correct.• The answer is true.• Other term for reinforcement is dispersive selection• The populations of birds will not be able to interbreed because they are different species.• The fitness of the large-beaked birds will increase and also it increases to possibility of creating new species.
The answer is B. evaporation
Answer:
Urbanization also affects the broader regional environments. Regions downwind from large industrial complexes also see increases in the amount of precipitation, air pollution, and the number of days with thunderstorms. Urban areas affect not only the weather patterns, but also the runoff patterns for water.
B- black allele;
b- brown allele;
The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb
The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being brown homozygote- bb- 25%
answer: 25%+25%=50% are homozygotes
