Answer:
75% of their offsprings will be red birds, and 25% will be with birds, this is the phenotype.
The genotype will be BB, Bb, and bb.
Explanation:
he information that we have is that B is the dominant allele for red feathers in a bird, and b is the recessive allele for white feathers in a bird.
If we cross two heterozygous birds that means that both progenitors are Bb, if we draw a Punnet Square we can see that 75% of the offsprings will be red birds, and 25% will be white birds, this is the phenotype, which is what we can physically see of the genes.
The genotypes will be BB, Bb, and bb, these are the different combinations of genes that can happen, and that explains why a bird is red or white, which is due to the dominance of one allele over the other.
<u> ║ B ║ b ║</u>
<u>B║ BB ║Bb ║</u>
<u>b║ bB ║ bb ║</u>
Nitrogen fixation is the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. In nature, most nitrogen is harvested from the atmosphere by microorganisms to form ammonia, nitrites, and nitrates that can be used by plants.
