Answer:
All eight phenotypes are possible but parental phenotypes will be more in number
Explanation:
In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:
- MDP/mdp
- Mdp/mdp
- mDp/mdp
- mdP/mdp
- MDp/mdp
- mDP/mdp
- MdP/mdp
- mdp/mdd
In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.
If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.
The word for people who study fossils are paleontologists and they may use paint brushes to clean fossils for soft sedimentaries.
Answer:
A) The catalyst makes lower energy pathways available.
Explanation:
A catalyst is a substance which speeds up a chemical reaction without itself being used in the reaction. Activation energy is the thresh hold energy which is required to initiate a chemical reaction. In the absence of catalyst, the activation energy is high therefore reactions are slower. But, presence of catalyst lowers the activation energy required to initiate the reaction as a result of which the reaction gets an alternate energy pathway to proceed which is responsible for speeding up the reaction.
Answer:
The correct answer is- Transduction
Explanation:
There are three processes by which genetic material of one bacteria can pass to the other bacteria and these processes are transformation, conjugation, and transduction.
In transduction bacteriophage( virus that infects bacteria) is responsible for the transfer of genetic material of one bacteria to another bacteria. When a virus infects one bacteria its genetic material divides with the bacterial DNA and sometime during making new phage particles part of bacteria DNA gets packed in viral capsid.
When that virus infects another bacteria the genetic material of other bacteria gets incorporated in its host genome and this process is called transduction.
