Suppose you have monohybrid flowers in your garden and find that they produce black seeds to brown seeds in the ratio of 3: 1. if the allele are designated (b & b) receptively, what are the probable genotypes of the black seeds produced by your plants?

the match duh

explanation:

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.
