Answer:

Barbasco plant.

Explanation:

Native people in the Amazon rainforest use a toxin extracted from Barbasco plant roots which is responsible to stun fish and make it slow to catch the fish easily. This method is used only on the small streams not on large river. This toxin helps in the slowing of the catfish which can't be catch without of this toxin because catfish is very active and quick which is hard to catch at this state so that's why the Native people in the Amazon rainforest use this toxin.

Now, suppose that the three tomato genes from Part A did not assort independently, but instead were linked to one another on the
Ksenya-84 [330]

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 process of ____________ increases genetic variability as it produces gametes for sexual reproduction.
otez555 [7]
The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the  offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.
