That Trait (Hitchhiker's thumb) may be recessive in both the parents but when they transmitted their genes to their offspring, it became dominant in that 'cause of two similar genes (Homozygous Condition).
Hope this helps!
Answer:
tt
Explanation:
Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.
tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.
So it would make sense that tt is the choice.
Answer:Self-assembly into a simple membrane
Explanation:
The cell membrane is the biological membrane that separates the interior of the cell to the exterior of the cell.
The cell membrane is made of lipid by-layer. The first cell membrane was made of lipids. It is so because it has the ability to assemble and form a membrane like structure.
It helps in entry and exit of the substances from inside of the cell to outside and vice versa.
Bio engineering has provided the ability to regrow tissue for knee or hip joints.
