I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is
Tt x tt (heterozygous crossed with a homozygous recessive)
The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.
So the percentage of offspring that are homozygous recessive is 50%.
Physical differences in beaks of birds would develop as a result of different environmental changes.
<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.
This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.

Answer:
False
Explanation:
Rearrangements on introns and transposons usually don't cause severe consequences because those sequences are not part of coding genes and therefore cannot code for proteins, and if a rearrangement occur within a coding sequence of a gene might cause an incomplete and non-functional protein causing severe consequences to expression levels of that particular gene.
Answer:
Proteins
Explanation:
They are found everywhere in the body from muscle, cell membranes, hair, enzymes, and etcetera and are responsible for the phenotype of organisms. Proteins are the ultimate expression of genes in the DNA of organisms. The DNA is transcribed by DNA polymerase into mRNA, then mRNA is translated into protein by ribosomes. This general rule is called the central dogma.
