In each of the scenarios, an individual heterozygous for the indicated gene or genes is crossed with an identical heterozygous i

ndividual. Predict the number of different phenotypes that would be observed among the progeny of such a cross.
Scenario 1 : R is completely dominant to r.
Scenario 2: R is codominant with r.
Scenario 3: R and S are completely dominant to rand s, respectively; R and S are linked by 15 m.u. and do not interact with each other.
Scenario 4: Genes R and S perform the same function; R and S are completely dominant to r and s, respectively; and R and S are unlinked.
Scenario 5: R and S are completely dominant to r and s, respectively; R and S are linked by 10 m.u. and show dominant epistasis.

What kind of tissue provides plants with the first line of defense against damage and disease?
sergeinik [125]


The best answer - dermal tissue.

Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.

Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.

Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.
