Meiosis, Mendel
Mutations, Meiosis,, and Mendel's genetics
| Question | Answer |
|---|---|
| What is a carcinogen? | substance capable of causing cancerous mutations in genes |
| What is an inversion mutations? | a mutation when a segment of a gene is broken then reinserted backwards |
| 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 |
| A Punnett Square showing a cross for one trait is called what | monohybrid cross |
| What are possible phenotypes for the children with a mother with type O blood and a father with type AB blood? | A or B |
| What do we call a trait that is determined by the effect of more than one pair of genes | polygenic |
| In a pedigree of three generations and 18 people, 10 females and 8 males, a trait is expressed in everyone except 1 boy and one girl. What would we call this type of trait? | autosomal dominant |
| What is referred to as a genotype? | the allele combination of an individual |
| What is referred to as a phenotype? | the physical expression of genotype...what it looks like |
