inheritance Flashcards
what are differences in characteristics called
variation
why might variation be different
inherited genes, environment, combination
what is a mutation
a change in a DNA sequence, occur continuously
what happens to a phenotype from a mutation
some might change to a suited environment and can lead to rapid change
what is the process of selective breeding
- choose parents with desired characteristic
- breed together
- choose offspring
- continue over generations until all offspring show desired characteristic
what’s a clone
been asexually produced, genetically identical to parent
why might the characteristic in selective breeding be chosen
disease resistance, produce more, pets with desired nature, larger/unique flowers
disadvantages of selective breeding
inbreeding- particularly prone to defects/diseases, reduces variation
process of adult cell cloning
Sheep A’s adult cell is collected and nucleus removed. Sheep B’s mature egg is collected and nucleus is removed. They receive mild electric shock
