MS1:

- Gamete is a reproductive cell (1)

- Example: sperm or egg cell (1)

MS2:

- Recessive alleles are masked by dominant alleles in heterozygous individuals (1)

- Recessive alleles only appear in the phenotype when homozygous (1)

- Example: carriers of genetic diseases have one dominant and one recessive allele (1)

MS3:

- DNA stores genetic information in the form of genes (1)

- Genes are located on chromosomes (1)

- Genes control the production of proteins (1)

- Proteins determine the phenotype of an organism (1)

MS4:

- Meiosis (1)

MS5:

- Genotype refers to the genetic makeup of an organism (1)

- Phenotype refers to the observable characteristics of an organism (1)

MS6:

- Mutations are changes in the DNA sequence (1)

- Mutations can create new alleles (1)

- New alleles can provide new traits that may be advantageous (1)

MS7:

- Theory of Natural Selection (1)

MS8:

- Individuals with desired traits are chosen for breeding (1)

- Offspring inherit the desired traits (1)

- Selective breeding continues over generations to accumulate desired traits (1)

MS9:

- Cloning involves creating an identical copy of an organism from a single cell (1)

- Potential uses include medical research, organ transplantation, and species conservation (1)

- Ethical concerns also need to be considered (1)

MS10:

- Species (1)
