Phenotype
The physical expression of the alleles
Chromosome
Chromosomes are thead like structures located inside the nucleus of animal and plant cells
Variation
A change or slight difference in condition amount or level typically within certain limits
Dominant gene
Some genes are stronger than the other so if you have brown eyes and brown hair and your dad had the same you would have a dominantgene
Homozygous

Heterozygous
Pair of alleles that priduce a characteristic are different eg Hh
Dominant

Recessive
An allele that will only be expressed when both allelses are of this type eg hh
Where is a chromosome found
Nucelus
Selective breeding can also be called
artificial selection
Another word for characteristics is
Traits
What is genetic engineering?
Genetic engineering is when your combine 2 animals charatistics together to produce somthing or do something simular to the other animal
