What is genetic crossing over? | when genetic information gets mixed up between homologous chromosomes |
What is a deletion mutation? | when one or more nucleotide bases are deleted from a sequence |
What is a mutation? | a permanent change in the nucleotide sequence in a chromosome |
New traits generally appear in a species due to these | mutations |
Genetic mutations that occur where will be passed on to offspring | gametes |
Genetic mutations in somatic cells most likely result in what | the wrong proteins created |
Cancer is caused by the disruption of which what cell function due to mutation? | DNA replication |
Not all genes are harmful, some are | beneficial |
Crossing over contributes to genetic diversity by | producing new allele combinations |
How much of an indiidual's DNA is inherited from the individual's father? | 50% |
Mendel discovered that alleles are not tied to each other and are able to mix independent of each other in gametes, we call this | The law of independent assortment |
Meiosis goes through two divisions to be left with what type of cells (diploid or haploid) | haploid |
Why is meiosis a benefit to species? | it allows more genetic variation |
