How would i use a punnett square to explain how a dominant allele masks the presence of a recessive allele

bc its dominant its stronger then recessive

Explanation:

An allele is considered dominant when it masks the expression of the recessive trait in a heterozygous genotype. When you are homozygous for a recessive allele, the phenotype expressed is the recessive trait. If you are heterozygous, one of each, the dominant trait is expressed.

there’s no image attached but i can if you want: )

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.
