Incomplete dominance, sex-linked recessive disorders, chromosomal mutations, and Mendel's Laws are concepts in which field of study?

Here are the answers for Question 2:

2.1 An advantage of genetic modification:
Genetic modification can increase the shelf life of food and increase resistance to disease.
Answer: $\boxed{\text{BOTH A AND B}}$

2.2 The genotype for an individual with blood group AB:
The genotype for blood group AB is $I^A I^B$, which includes both alleles $I^A$ and $I^B$.
Answer: $\boxed{\text{BOTH A AND B}}$

2.3 Inheritance of haemophilia:
Haemophilia is a sex-linked recessive disorder.
Answer: $\boxed{\text{A ONLY}}$

2.4 Caused by a chromosomal mutation:
Colour-blindness is caused by a gene mutation, while Down syndrome is caused by a chromosomal mutation (trisomy 21).
Answer: $\boxed{\text{B ONLY}}$

2.5 Unspecialised cells that have the potential to develop into any other type of cell in the body:
These are stem cells. Somatic cells are specialised body cells.
Answer: $\boxed{\text{A ONLY}}$

2.6 An organism possesses two factors which separate so that each gamete contains only one of these factors:
This describes Mendel's Law of Segregation. Neither the Law of Dominance nor the Principle of Independent Assortment directly describes this.
Answer: $\boxed{\text{NONE}}$

2.7 A plant with white flowers that is crossed with a plant with red flowers and produces offspring with pink flowers:
This is an example of incomplete dominance, where the heterozygous phenotype is intermediate between the two homozygous phenotypes.
Answer: $\boxed{\text{A ONLY}}$

2.8 The separation of alleles during gamete formation:
This is described by Mendel's Principle of Segregation.
Answer: $\boxed{\text{B ONLY}}$

2.9 A genetic disorder caused by a chromosomal mutation:
Haemophilia and colour-blindness are both caused by gene mutations, not chromosomal mutations.
Answer: $\boxed{\text{NONE}}$

2.10 The type of dominance in which neither of the two alleles is dominant over each other, resulting in an offspring with an intermediate phenotype:
This describes incomplete dominance. Complete dominance means one allele masks the other, and co-dominance means both alleles are expressed equally.
Answer: $\boxed{\text{NONE}}$

2.11 The scientist who proposed the law of segregation:
The Law of Segregation was proposed by Gregor Mendel. Darwin and Lamarck are known for theories of evolution.
Answer: $\boxed{\text{NONE}}$
