Which of the following resulted from codominance? 1)a person with AB blood type 2)a flower with pink petals 3)a rabbit with white fur 4)a mouse with brown fur

Answers

Answer:

The correct answer would be 1) a person with AB blood type.

Codominance is the condition in which both the alleles of the gene express themselves completely in the heterozygous condition.

AB blood group can be a perfect example of the codominance. Both the alleles (A and B) express themselves completely and lead to the formation of protein A (or antigen A) and protein B (antigen B) on the surface of the red blood cells.

Which best explains the evolution of gymnosperm plants?A.They evolved along with monocots and dicots.
B.They evolved after the seeded flowering plants.
C.They evolved after the seedless vascular plants.
D.They evolved before the seedless nonvascular plants.

Answers

The answer to this question about the evolution of the gymnosperm plants would be C. They evolved after the seedless vascular plants.

Gymnosperms, or sometimes termed as seed plants, are classified as vascular plants and has been thriving for centuries on earth through producing seeds. They are multicotyledonous and are the opposite of flowering plants. Conifers would be the most abundant group of gymnosperms while the cycads come in second. Gingko would place last with just having one species under its name.

The statement that best explains the evolution of gymnosperm plants is that they evolved after the seedless vascular plants.

What are gymnosperms?

Gymnosperms are classes of plants that do not produce fruits but rather bear seeds structures called cones.

Gymnosperms and angiosperms both belong to the class of plants called higher plants because they have mechanisms for conducting and transporting water and nutrients.

Gymnosperms are believed to evolve before angiosperms or flowering plants but after seedless vascular plants called pteridophytes.

Therefore, the statement that best explains the evolution of gymnosperm plants is that they evolved after the seedless vascular plants.
