| show | A human karyotype will have 23 pairs(46 chromosomes)
🗑

| How can you tell if a karyotype is male or female? | show 🗑
|
||||
| show | they are made by taking a photograph of the chromosomes in a nucleus, cutting out each chromosome, and reorganizing the into pairs.
🗑
|
||||
| show | they are organized by length(longest to shortest), banding pattern, and where the pinch is.
🗑
|
||||
| How do karyotypes of different organsisms differ? | show 🗑
|
||||
| show | every egg cell has 1 x cell. For every two sperm made, one has an x chromosome and one has a y chromosome. so 50% of the sperm have an x and the other 50% have a y.a boy is xy and a girl is xx so whichever 1 of every two sperm gets the egg, decides gender

| What is a zygote? | show 🗑
|
||||
| show | one fertilized egg cel splits into 2 zygotes for an unknown reason.
🗑
|
||||
| show | fraternal twins are created when two different egg cells are fertilized.
🗑

| Why can a child not look exactly like one parent? | show 🗑
|
||||
| Why are twin studies so helpful when trying to figure out if a trait is genetic, environmental or multifactoral? | show 🗑
|
||||
| What is the relationship between ribosomes and chromosomes? | show 🗑
|
||||
| show | The capital letter(I) is the dominant gene, and the lowercase letter(i) is recessive. So unless you have two of the recessive, you don't even know you have it because the dominant gene takes over. with(F1) there are no doms. you just combine.
🗑
|
||||
| show | blood type, eye color, natural hairline
🗑
|
||||
| show | clothing preferance, preferance of a tv show, favorite soda brand.
🗑

||||
| show | genetic b/c it is decided by your chromosomes. you have a gene in a chromosome inherited from parents for eye color. environmental b/c you don't have a gene for it, the trait is completely decided by your environment.
🗑

||||
| show | a trait that is deided by your genes and by the environment. Hair form- you might have naturally curly hair(genetic) but like the way it looks straight so you striaghten it(environmental.)
🗑
|
||||
| show | The nucleus holds chromosomes which are the plans for creating new chromosomes in cell division.
🗑
|
||||
| What happens to to the chromosomes of a body cell making sex cells? | show 🗑
|
||||
| show | each new body cell gets the same number of chromosomes as the original body cell.
🗑
|
||||
| show | When cells die, it is important they can be replaced and we need to grow(new cells)
🗑
|
||||
| show | both create two new cells.
🗑
|
||||
| show | body gets all chromosomes, sex gets half.
