Need help with this ! Thank you

The first filial generation is Tt, Tt, tt, tt

Explanation:

The gene Tt seperate to yield two alleles "T" and "t"

The gene tt seperate to yield two alleles "t" and "t"

Then, each of the alleles goes into each space on the side and top. On crossing, the space would contain Tt, Tt, tt and tt

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
