Answer: is heterozygous
Explanation: A hybrid is heterozygous which means that it has one dominant gene and one recessive gene. A dominant gene is a type of gene which has the ability to express itself phenotypically either in a homozygous or a heterozygous state. A dominant gene masks the effect of a recessive gene. A recessive gene is a type of gene that lacks the ability to express itself in a heterozygous state. It can only express itself outwardly in a homozygous state. It's effect is masked by the dominant gene is a heterozygous state.
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>
I believe it is 'white fur' because living in the Tundra means it is snowing. Snow is white, so basically, the white fur is specifically for the Tundra.
I hope it helps.
Tape worms have numerous adaptations to enhance their survival in the hosts.
For example the have anatomical adaptations in the form of scolex with hooks that they use to attach to the host small intestine walls therefore preventing them from being excreted following peristalsis. Therefore, the correct answer is that they posses hooks that they use to attach to the small intestines.
