In a reading frame, one base is misplaced for another.
But in a frameshift mutation, a base is added or removed.
Remember, codons are groups of three, and they code for amino acids. In frameshift mutations, another base is added and that completely shifts the frame. Hence, the amino acids are messed up, and so is the protein made from it.
Answer:
B
Explanation:
competing for resources better helps the organism survive
Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
Explanation:
When fats are used as a substrate in respiration, the RQ is less than 1 because the amount of oxygen utilised is always higher than the amount of carbon dioxide released.
