Answer:
The correct answer is - Genotype : 100 heterozygous (TtRr) and
Phenotype: 100% tall pink.
Explanation:
A cross between dwarf red snapdragon (ttRR) and homozygous tall white plant (TTrr) will form gametes tR and Tr. These gametes fuse and form Heterozygous condition for both traits that is TtRr.
TtRr snapdragons will form tall and pink phenotypically as we know T (tall) is dominant over t (dwarf) and heterozygous condition will be tall. But in condition of color Heterozygous form pink flower.
Thus, the genotype of offspring will be TtRr and phenotype will be all tall and pink for better understanding check punnet square.
Selective breeding and <span>natural selection are similar because they are both giving certain traits to offspring.
DIFFERENCE:
</span>natural selection-Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest
selective breeding-Selection by humans for breeding of useful traits from the natural variation among different organisms
Earth's orbit and climate change.
Eukaryotic cells have membrane-bound organelles which carry out cell functions, a Nucleus which contain DNA from the cells and a cytoplasm which is similar to a jelly like fluid interior of the cell. It also has a cell membrane which is basically an outer boundary for the cell.
I believe it is D. More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory.
