Vision
these cells in your eye let you see color.
what are Cone cells?
A sagment of DNA that provides instructions for a specific trait, such as eye color or height
What is a gene?
What is a distinguishing characteristic that an organism can pass on to its off spring
What is a trait?
What tool do scientists use to predict the probability of traits in a offspring?
What is a punnet square?
A specific version or from of a gene
What is and Allele?
The colored part of the eye that controls how much light enters by adjusting the size of its center
What is the iris?
The word for a feature that can be passed down from parent to offspring
What is an inherited trait?
Give examples of an inherited trait
what is eye color, hair color or height?
In a punnet square, what goes on the outside of the grid?
What is the parents genotypes?
this type of trait is always expressed or shown if the specific allele is present
What is a dominant trait?
This is the opening in the center in the center of the iris that looks like a black dot and lets light into the eye
What is the pupil?
A type of gene that is fully expressed and overpowers a recessive gene.
What is a dominant gene?
What do you call a characteristics that are learned or developed over an organisms lifetime, like riding a bike?
What is an acquired trait?
If one parent is TT and the other parent is TT, what are all the possible genotypes for their offspring?
What is Tt (100%)?
This type of trait "Hides" in the background and is only expressed if an organism has 2 copies of this allele.
What is a recessive trait?
The retina contains these two types of light receptor cells, one helps you see black and white and the other helps with color
WHat are rod and cone cells?
A type of gene that is hidden or masked whenever the dominant gene is present
What is a dominant gene?
True or false: Liking a specific type of food or having a scar from falling down are inherited traits.
FALSE they are acquired
Two heterozygous parents (Bb and Bb) are crossed. What is the probability that their offspring will be homozygous recessive (bb)?
What is 25%?
We use this type of letter like "B" to represent the dominant alleles.
What is an uppercase letter?
This clear domed shaped tissue forms the outer layer at the front of the eye and helps focus incoming light
what is the cornea?
The handy, grid like tool scientists use to predict the probability of possible genotypes and phenotypes for offspring.
What is a punnet square?
If brown eyes are dominant (B) and blue eyes are recessive (b), what color eyes will a person with the alleles Bb have?
What is brown?
If a homozygous dominant parent (BB) is crossed with a heterozygous parents (Bb), what is the probability of the offspring having the dominant Phenotype?
What is 100%?
We use this type of letter like "b" to represent recessive alleles.
What is an lowercase letter?
