🗑
|
||||
| What is a hybrid? | A mix of two alleles
🗑
|
||||
| what are the male sex chromosomes | XY
🗑
|
||||
| What is an allele? | the different form that a gene can be for a specific traits (shows different forms in a population)
🗑
|
||||
| In a punnett square what does a capital letter stand for? | Dominant allele
🗑
|
||||
| who is the father of genetics | Gregor Mendel
🗑
|
||||
| For a dominant genetic disorder, how many parents need to have the disorder | one parent
🗑
|
||||
| When there are two BIG alleles, it is said to be : | homozyogous dominant
🗑
|
||||
| Describe Mendel's first experiment | a cross between a true-breeding purple pea plant and a true-breeding white pea plant= ALL purple pea plants
🗑
|
||||
| When to alleles are small they are said to be: | homozygous recessive
🗑
|
||||
| What is incomplete dominance? | When two different alleles mix or blend together
🗑
|
||||
| List three reasons why Mendel choose to study peas | 1. they grow fast 2. self-pollinate 3. many different types
🗑
|
||||
| What is a self-pollinating plant? | A plant that can pollinate itself, doesn't need external factors
🗑
|
||||
| What is probability? | The chance (likelihood) that a possible event can occur
🗑
|
||||
| What is the percent change of having a female? | 50 % chance
🗑
|
||||
| What is a trait? | Different forms of a characteristic
🗑
|
||||
| Where are genes located? | chromosomes/DNA
🗑
|
||||
| What is an gene? | Instructions for an interited trait
🗑
|
||||
| What is heredity? | The passing of genetic material from parent to offspring (generation to generation)
🗑
|
||||
| What allows variation in a population? | Genetics, sexual reproduction (mixing different characteristics and traits)
🗑
|
||||
| In a punnett square, a little letter represents what? | a recessive allele
🗑
|
||||
| What is a diagram that is used to trac a trait through generations in a family | pedigree
🗑
|
||||
| a chart that is used to predict the possible outcomes of offspring of a cross between two parents | punnett square
🗑
|
||||
| describe Mendel's second experiment | Took one plant from the first generation and self-pollinated it Pp x Pp = PP, Pp, Pp, & pp (3 purple and 1 white)
🗑
|
||||
| What is a characteristic? | a feature that has different forms in a population
🗑
|
||||
| Which is more general; a characteristic or a trait? | Characteristic
🗑
|
||||
| What is an organism's genetic makeup? | genotype
🗑
|
||||
| When to alleles are homozygous they are said to be the: | SAME (same information from both parents)
🗑
|
||||
| When to alleles are heterozygous they are said to be the: | DIFFERENT (Different information from both parents)
🗑
|
||||
| What is an organism's genotype? | Genetic Make up (such as Hh, the letters that represent the information)
🗑
|
||||
| What does purebred mean? | When the alleles are the SAME, (same definition as homozygous)
🗑
|
||||
| Where are genes found? | On chromosomes or in DNA
🗑
|
||||
| What is incomplete dominance? | When to alleles mix or blend together to get a new trait. The dominant trait does not take over. For example red and white mix to make pink.
🗑
|
||||
| Where are sex-linked traits found? | on the X chromosome
🗑
|
||||
| Who is more likely to get a sex-linked disorder? | Males, because they only have one "X" Chromosome. And in order to get a sex-linked disorder all of the person's X's need to be infected
🗑
|
||||
| How does someone get a dominant genetic disorder? | One parent needs to carry the defective copy of the gene on the dominant allele.
🗑
|
||||
| Is a dominant or recessive genetic disorder more common? | Dominant, because only one parent needs to show it
🗑
|
||||
| How does someone get a recessive genetic disorder? | Both parents need to show or carry the defective copy of the allele.
🗑
|
||||
| Show an example of what a recessive disorder would look like if the person showed it in a punnett square | a* a*
🗑
|
||||
| Show an example of what a dominat disorder would look like if the person showed it in a punnett square | A * A or A* A*, or A* a
🗑
