Genetics

Question 1

Homozygous

Answer 1

having 2 identical alleles for a particular characteristic

Question 2

Dominant Allele

Answer 2

An allele that has an effect in both heterozygous and homozygous conditions

Question 3

genotype

Answer 3

The genes/alleles that an organism posseses

Question 4

Recessive Allele

Answer 4

an allele which only has an effect in the homozygous condition

Question 5

Recessive Allele

Answer 5

an allele which only has an effect in the homozygous condition

Question 6

Phenotype

Answer 6

An organisms outward appearance/characteristics

Question 7

Heterezyogous

Answer 7

Having 2 different alleles for a particular characteristics

Question 8

Alleles

Answer 8

Different forms of the same gene

Question 9

Homozygous recessive

Answer 9

having 2 of the same identical recessive alleles

Question 10

Homozygous dominant

Answer 10

having 2 of the same identical dominant alleles

Question 11

Homologous pairs

Answer 11

a pair of chromosomes that have the same genes at the same loci, but alleles could be different.
Or
The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles.

Question 12

Expressed

Answer 12

gene is switched on, the protein is made and the characteristic/trait is seen/present in the phenotype

Question 13

Pure breeding

Answer 13

Organism is homozygous and can only pass 1 type of allele to its offspring
