This is true, Darwin spent over 20 years developing his theory of natural selection
If you will make a Punnett square for this problem it will look like this:
T t
t Tt tt
t Tt tt
So the genotype in the first and third box would be Tt. On the second and fourth box, we have tt.
So your answer would be: C. 1 = Tt; 2 = Tt; 3 =tt; 4 = tt
The differences between the two groups of the same species may be influenced by their genetic differences (such as allelic frequencies) and their environment
Individuals of the same species may differ in the following characteristics;
- Fertility – on the population may a higher frequency of recessive alleles that reduces their rate of reproduction
- Metabolism – this also may be determined by the type of allele
- Physical appearance – the influence of the environment in which the population habits on the genotypes of the population
- Behavior – this is mostly determined by the environment.
- Learning - this is also determined by the environment
Meat, seafood, beans, etc...
