Pls

which punnett square shows the correct cross between a homozygous tall plant and a short plant?

The correct Punnett square is the second, with the traits

T,T and t,t.

Your Four Gene Codes in the Punnet square would be

Tt,Tt,Tt,Tt.

How I am able to remember this is by the words Homozygous and Heterozygous, I learned the trick to them awhile ago.

Homo= Same

Hetero= Not The Same

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

d. organisms have cells with different shapes and functions.
