MS1:

- An allele is an alternative form of a gene at a specific locus on a chromosome.

MS2:

- Heterozygous individuals have two different alleles for a gene, one dominant and one recessive (1)

- The dominant allele masks the expression of the recessive allele in the phenotype (1)

MS3:

- Meiosis is a type of cell division that reduces the chromosome number by half (1)

- It involves two rounds of division (1)

- It results in the formation of haploid gametes (sex cells) (1)

MS4:

- Genotype is the genetic makeup of an organism (1)

- Phenotype is the observable traits of an organism (1)

MS5:

- Natural selection acts on variations within a population (1)

- Individuals with advantageous traits survive and reproduce more than others (1)

- Over time, these advantageous traits become more common in the population (1)

MS6:

- Potential benefits include improved treatments for diseases and new therapies (1)

- Ethical concerns include potential risks to human health and the environment (1)

- It is important to weigh the potential benefits and risks carefully (1)

MS7:

- Cloning (1)

MS8:

- Lamarck believed that acquired traits could be inherited (1)

- However, modern genetics has shown that acquired traits are not generally passed on to offspring (1)

MS9:

- Selective breeding involves mating individuals with desirable traits (1)

- The offspring of these individuals inherit the desired traits (1)

- This process can be repeated over generations to improve crop yields (1)

MS10:

- Nucleus (1)
