What is a recombinant phenotype?

What is a recombinant phenotype?

A recombinant phenotype is just a phenotype that is not identical to one of the parents. So, say a long green plant is crossed with a short yellow plant and one of the offspring is short and green, it has a recombinant phenotype because none of the parents show it. The offspring that are short yellow and long green would just have parental phenotypes.

Cytosol and cytoplasm.
What are the differences?

Getting confused  :/

Thank you

Thank you

Just think of it this way. Cytosol is a part of the Cytoplasm. More specifically, the cytosol is the fluid-like inside of the cell. The Cytoplasm is more of a collective term for the Cytosol including the organelles suspended within the Cytosol.

What is the meaning and difference  between internal environment and the external environement?

What is the meaning and difference  between internal environment and the external environement?

Well it depends. The internal environment of an organism is the extracellular/interstitial/plasma fluid in which its cells are surrounded by. The external environment is everything else.

The internal environment of a cell is the cytosol within, whereas the external environment is the extracellular fluid which surrounds the cell.

Confusing? It is.

haha thanks - yes definitley confusing lol

Do the same restriction enzymes create the same sticky ends or do they create complementary sticky ends?

How is DNA ligase used to create recombinant DNA?

Oh, and a simple way of remembering cytosol and cytoplasm:

cytosol: fluid
cytoplasm: fluid + organelles (excluding nucleus I think)

has anyone done a prac that involves using a computer, and using that data to complete a question/answer test? (basically two parts: acquiring data, then being tested based on ur results) ***for heredity/meiosis/mitosis

[howlingwisdom]

How is DNA ligase used to create recombinant DNA?

DNA ligase basically acts as glue and joins the cut plasmid vector with gene of interest (which'll both have complementary sticky ends because they were cut from the same restriction enzyme)

I had a surprise SAC today
(Did not study one bit for it. Why? Because I DIDN'T KNOW ABOUT IT.)

[RazzMeTazz]

How would you define Co dominance?

are surprise SACs even allowed?!?!

What would be an example of multiple alleles in plants?

What would be an  example of polygenic inheritance in plants?

[howlingwisdom]

How would you define Co dominance?

Co-dominance is when the traits are expressed equally in a heterozygote (e.g blood groups A and B)
