Answer:these are biological inheritance
Explanation:
Answer:
I think its Carbon-Dioxide-Oxygen
Explanation:
Answer:
Ionic compounds are formed by the transfer of elecrons from highly electropositive element to highly electonegative element.
Covalent compounds are formed by the shairing of electrons between elements.
Explanation:
Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
Answer:
Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.
Explanation:
Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.
In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.
