In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farme

irina1246 [14]

Answer:

a. Genotype in F1 - TtBb

Phenotype in F1 - tough pods, bush-type growth

b. Proportion of F2 that are heterozygous for bush-type growth form = 5/8

c. Proportion of the F2 with tender pods = 1/4

d. Proportion of F2 that are heterozygous for growth form and have tender pods = 1/8

Explanation:

Since the two traits are located on different chromosomes, they will independently assort during gametes formation. T is dominant over t and B is dominant over b.

Two true-breeding varieties were crossed at the beginning of the program:

TTBB x ttbb

All F1 plants will have the genotype TtBb with tough pods and bush-type growth form.

Advancing the cross to F2:

TtBb x TtBb

Progeny

1 TTBB - tough pods, bush-type

2 TTBb - tough pods, bush-type

2 TtBB - tough pods, bush-type

4 TtBb - tough pods, bush-type

1 TTbb - tough pods, climbing-type

2 Ttbb - tough pods, climbing-type

1 ttBB - tender pods, bush-type

2 ttBb - tender pods, bush-type

1 ttbb - tender pods, climbing-type

Proportion of F2 that are heterozygous for bush-type growth form = 10/16 = 5/8

Proportion of the F2 with tender pods = 4/16 = 1/4

Proportion of F2 that are heterozygous for growth form and have tender pods = 2/16 = 1/8

What effect does epinephrine/norepinephrine have on the alpha receptors of the iris of the eye or the skeletal muscle vasculatur

Ulleksa [173]

Answer: When norepinephrine binds to alpha receptors of the iris of the eye, it causes contraction of the ciliary muscles of the eye which brings about pupil dilation.

Stimulation of alpha receptors of the smooth muscle vasculature results in vasoconstriction of blood vessels.

Explanation: Alpha receptors are adrenergic receptors that respond to norepinephrine. They are subdivided into two (2) types:

Alpha 1, found in smooth muscle heart, liver, pregnant uterus, male sexual organs and blood vessels, with effects including vasoconstriction, intestinal relaxation, uterine contraction and papillary dilation.

Alpha 2, found in platelets, vascular smooth muscle, nerve termini and pancreatic islets, with effects including platelet aggregation, vasoconstriction and inhibition of norepinephrine release and of insulin secretion.
