Genetic inheritance

What is an allele?

1. A small section of DNA on a chromosome that controls the characteristics
2. A different form of gene that codes for different proteins
3. The combination of alleles present in an organism

What is an gene?

1. A small section of DNA on a chromosome that controls the characteristics
2. A different form of gene that codes for different proteins
3. The combination of alleles present in an organism

What is a genotype?

1. A small section of DNA on a chromosome that controls the characteristics
2. A different form of gene that codes for different proteins
3. The combination of alleles present in an organism

What is a gene?

1. Small pieces of alleles
2. Small sections of DNA

These are located on chromosomes

1. Nucleus
2. Cell
3. Genes
4. Chromosomes

What do genes control

1. Hair length
2. Dyed hair colour
3. Hair style
4. Natural hair colour

What is an allele?

1. A part of a gene
2. A different form of a gene

What do alleles code for?

1. They code for different enzymes
2. They code for different carbohydrates
3. They code for different proteins
4. They code for different sugars

What do alleles influence

1. The traits we can see (eye colour)
2. The traits we cannot see (accent)

Genotype is

1. Combination of alleles in an organism
2. Observable characteristics
3. Determines phenotype

Phenotype is

1. Combination of alleles in an organism
2. Observable characteristics
3. Determines phenotype

Genotype controls

1. The genotype
2. The phenotype
