As you can see in the diagram presented below, the correct genotypes of the parents are TT and Tt.
Each parent give its children only one chromosome of the chromosome pair, therefore only one allele of the gene.
In our case, TT and Tt is the correct answer because one of the parents has to have the t allele to give to the Tt offspring.
But if both of the parents were Tt, one of the offspring would have tt genotype, and if the parents were TT and tt, all of the offspring would be Tt. Therefore, the TT x Tt combination is the only possible answer.
The first box is migration
The second box is the northern regions have become warmer because of climate change
Answer:
The frequency would be stable.
Explanation:
Based on the most common symptoms of cystic fibrosis, the disease only appears on adults and elderly. This feature means that the frequency of the disease would not drop or raise because they would still reproduce and pass the allele from generation to the next, maintaining the frequency stable.
When an organism reproduces they pass on their genetic information in the DNA to their<span> offspring.

The effect of a neurotransmitter is based on the properties of the receptor more than the neurotransmitter.
