Answer:
A) Madison’s parents’ blood types may be either A & 0, or A & A.
B) Depending on her parents’ genotypes, Madison’s genotype may be either AA or A0
Explanation:
Since the A allele is dominant with respect to the 0, a person with blood type A may have either one (A0 genotype) or two A alleles (AA genotype). In contrast, a person with blood type 0 may only have two 0 alleles (00 genotype).
Because one of the sisters has type 0 blood, we have to assume that both of her parents have at least one 0 allele. There are two situations which may give rise to the described scenario (see Punnett squares):
Alternative 1: One of the parents has A blood type (A0 genotype), and the other has 0 blood type (00 genotype). Madison’s genotype may only be A0.
| 0 | 0

A | A0 | A0

0 | 00 | 00
Alternative 2: Both parents have A blood type and A0 genotypes. Madison’s genotype may be either A0 (probability of 2/3) or AA (probability of 1/3).
| A | 0

A | AA | A0

0 | 0A | 00

How does the indents appearance affect its survival
Answer:
C. Niche overlap is small and the carrying capacities are similar.
Explanation:
The Lotka-Volterra model is used to predicts if coexistence of two species is possible .The Lotka–Volterra models show that coexistence is more likely if niche overlap is small and the carrying capacities are similar.
