Homozygous recessive: tt
Heterozygous: Tt
Cross:
t t
T Tt Tt
t tt tt
Thus, the expected outcome genotypic ratio is:
1 Tt : 1 tt
Answer:
this study is clearly an observational work
Explanation:
experimental studies involve to establish direct associations between a traits and its phenotypic effects. For example, a classical experimental study would involve to map a nonsense mutation in the ACTN3 gene significantly correlated to the non-sprinting phenotype
<span>Glossitis is basically swelling/ inflammation of your tongue
</span><span>Deficiency is basically something wrong, not right, lacking</span>
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>

Answer:
tissues, sports drink containers, compact disks, computers, cotton T-shirts, sneakers, fans, track pants, and light bulbs.
Hope this helps :)
