Hi there!
Using the image below, you can see that all of the boxes are Tt, or heterozygous. Therefore, 1 = Tt, 2 = Tt, 3 = Tt, and 4 = Tt.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Bad mutation: deletion/addition mutation
Good mutation: silent mutation
Explanation:
Addition or deletion mutation results in the reading frame of codons to be changed, leading to a extensive missense mutation that will lead to a non-functional protein product to form.
Good mutation are silent mutations that leads to no change to the final product but causes codons to change in sequence. This increases genetic diversity in the gene pool that enables the species to be more resilient to environmental changes.
Answer: biotic factors include plants and animals. So, the rainforest animals are more adapted to warmer weather meaning they have less fur and are built for warmer weather. The plants in a rainforest need lots of water to survive as well as carbon dioxide so they have large, wide leaves.
In a Taiga biome, the animals have more fur and adaptations to help them to survive in colder weather. The plants primarily consist of fir and pine trees, which have waxy, needle-like leaves to retain water as well. The trees also dont lose their leaves in the winter.
Explanation:
The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
