It's in your genes!
Blue eyes, green eyes, brown eyes, oh my! These are different forms of the eye color gene. We use this term for different versions of the same gene.
What are alleles?
Asexual reproduction involves this many parents.
What is one?
During prophase, DNA condenses into chromosomes, and this organelle breaks down.
What is the nucleus?
Say a fly has one allele for red eyes and one allele for white eyes. If the fly's eyes are red, then eye color follows this pattern of dominance.
What is complete dominance?
If you wanna win, sometimes you just need to be better than the competition. This term describes a trait that always wins if at least one of its alleles is around.
What is a dominant trait?
Genetic variation results from this form of reproduction.
What is sexual reproduction?
Single-file, please! This phase of mitosis puts your cell's chromosomes into an orderly line.
What is metaphase?
If you have a trait that is a mixture of traits from both of your parents, then we would say that the gene involved is following this pattern of dominance.
What is incomplete dominance?
When we say an allele is recessive, we're saying you need this many copies of that allele to produce a recessive trait.
What is two?
Better together! A sperm cell joins with an egg cell in this process.
What is fertilization?
Before mitosis can even start, DNA needs to be duplicated. This stage of the cell cycle prepares the cell for mitosis.
What is interphase?
YOU get to express your trait. And YOU get to express your trait! This pattern of dominance happens when two different alleles both express their traits at the same time.
What is codominance?
It's in your genes...except when it isn't. We use this term for a trait that is learned or experienced, rather than inherited through your genes.
What is an acquired trait?
A stable, unchanging environment is perfect for this type of reproduction to shine.
What is asexual reproduction?
Three feet apart, please! The cell tells chromatids to socially distance during this phase of mitosis.
What is anaphase?
A farmer's red-haired cow and white-haired cow have offspring. Thanks to codominance, we wouldn't be surprised to see this coloration in the offspring's hair.
What is red-and-white?
RR, Yy, aa. These are pairs of alleles that you inherited from your parents. Each pair of alleles is an example of this.
What is a genotype?
It's alive! When a sperm cell joins with an egg cell, the first cell of a new organism is made. We use this term for that cell.
What is a zygote?
When mitosis is all said and done, this process splits the cell into two.
What is cytokinesis?
An organism's eye color gene has FOUR possible alleles: red, yellow, green, and blue. The organism's eyes are purple thanks to incomplete dominance...and these two alleles.
What are the red and blue alleles?
