What is the genotype of the parent with orange eyes and white skin? (note: orange eyes are recessive.) p generation is orange eyes, white skin crossed with black eyes, green skin. f1 generation is all black eyes, green skin.

The given question says that one of the parents has orange eye and white skin.

The orange skin is recessive.

After crossing the orange eye white skin parent with black eye green skin parent we get F1 generation as black eye and green skin.

This suggest that the progeny of F1 generation is heterozygote for both the trait and express dominant phenotype.

Hence, the green skin is dominant over white skin.

All progeny would have a genotype

The picture shows a possible cross between orange eye white skin parent and black eye green skin parent.

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.
