The recombinat types are AB, and ab.
Genetic recombination involves the production of offspring with combinations of traits that differ from those found in either parent. In our case the parents are Ab and aB, which is not the same as the offsprings (AB,ab). During meiosis in eukaryotes, recombination involves the pairing of the homologous chromosomes a process.
Answer:
Option 1.
Explanation:
r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared with k selected species.
Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.
Thus, the correct answer is option (1).
<span>Any type of pharmaceutical product or dietary supplement must be tested in clinical trials before they can be marketed in order to assess their safety for the general public's consumption and to confirm their intended purpose. While not a complete fail safe, these tests intend to prove a reasonable sense of safety for the product.</span>
the answer would be d. a start base triplet
hope this helps:)
