WILL MARK BRAINLIEST!! HELP ME PLS I DON'T GET THIS What is the genotype and phenotype ratio for this cross?

Genotype ratio Tt:tt=1:1

Phenotype ratio 1:1

Explanation:

the phenotype ratio should be 1:1 since there are 2 individuals with the dominant allele and 2 without it

The genotype ratio should be 1:1 for the same reason

b is the best answer for this question.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
