Answer:
TTYy x TTYy and TtYy x TtYy
Explanation:
Cross between two the two plants yielded yellow and green plant in the ratio 296:104.
296:104 is approximately equal to 3:1.
According to Mendelian law, 3:1 ratio of dominant to recessive phenotype results from a cross involving two heterozygous individual.
Taking the seed colour into consideration, a cross between two heterozygous individual will be:
Yy x Yy = YY, 2Yy and yy
Ration of yellow to green = 3:1
<em>Hence, </em><em>option b</em><em> and </em><em>option d</em><em> are most likely to be the genotypes of the parent because both shows the genotype of seed colour in heterozygous conditions. </em>
Answer:.
A test-cross can reveal an unknown genotype. As the plants are heterozygous they sort independently of each other. when they are cross linked dominant genes express themselves in most of the cases whereas the recessive genes also express themselves resulting in the formation of tall and yellow plants and as well as short and green plants.
Explanation:
The impact of a single gene on more than one characteristic is called pleiotropy. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring.Mendel called the dominant allele the expressed unit factor; the recessive allele was referred to as the latent unit factor.Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. The recessive trait will only be expressed by offspring that have two copies of this allele and these offspring will breed true when self-crossed.
Specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish. It is a correct statement.
<h3>What is the effect of macrophages on zebrafish?</h3>
There is an inflammatory response to tissue injury. It is an important part of the process of repair. Scar tissue deposition is a direct downstream consequence of this kind of response in several tissues including the heart tissue.
Adult zebrafish do not only have the ability to regenerate lost cardiomyocytes. They can also remodel and resolve a scar which is extracellular, in tissues like the heart. This resolution of the scar is a poorly understood process.
Therefore, specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish.

Answer:
75% i think
Explanation:
because if it is dominant its most likely always gonna be that
Answer:
False
Explanation:
Due to the fact that all the organisms are connected in a chain, the energy flow would be affected and that would result in many organisms being deprived of energy they need and that creates a chain effect.
