Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.
Answer:
C. cell- tissue- organ- organ- system
Let "r" stand for the recessive red hair trait. A person with red hair must have a genotype of "rr" ( one from each parent) in order to have red hair( red hair being the phenotype).
Let "B" stand for brown hair and "b" stand for not brown hair. A person with brown hair can have a genotype of "Bb" or "BB" and have a phenotype of Brown hair. This is becasue brown hair "B" is the dominant trait.
The Hardy – Weinberg principle
has seven conditions that should occur in the evolution of the population. One
is when mutation does not happen. Two, is when natural selection is not
occurring. Three, if the population is infinitely large. Four, if all the
members of the population produce offspring.
Five, sexual intercourse is random. Six, the population will produce the
same number of offspring. And lastly, the population does not migrate from one
place into the other. The thing that would disrupt the genetic equilibrium is
the mutation.
