Punnet Square
HAIR COLOR - Blonde = dominant Brown = recessive
If one parent has Tt and the other has TT what percent chance will the offspring have blonde hair
What is 100%
The two blood type alleles must be the same
What is false
Structures on the tongue that contain the receptor cells for taste
What are taste buds
If one parent has freckles does the offspring have to have them
What is No
A method of reproducing where the offspring gets half their genes from each parent at random
What is sexual reproduction
EYE COLOR - Green = dominant Blue = recessive
If one parent has TT and the other has TT what percent chance will the offspring have blue eyes
What is 0%
If one parent has A and the B, what will the offspring have
What is type AB
A detectable change in the environment. For EX:, light, sounds, touch, chemicals etc.
What is stimulus
If the child can curl her tongue, but her parents can't how did she get that trait
Her parents carry the recessive gene to be able to curl the toungue
Light sensitive receptor proteins found in cone cells that send signals to the brain to translate
What are opsins
PTC - Yes = dominant No = recessive
If one parent has tt and the other has tt what percent chance will the offspring have no PTC
What is 100%
The allele an offspring gets is random
What is true
The 20 different building blocks which make up all proteins in the body
What are amino acids
If mom is colorblind and has a son will he be colorblind as well
What is Yes!
A set of instructions that describes what amino acids to string together in a specific order to make a given protein.
What is a genetic code
SUNBURN - Yes = recessive No = dominant
If one parent has tt and the other has Tt what percent chance will the offspring be able to tan
What is 50%
What's the only way to have type O
Both parents have to have type O
A nerve that carries signals from the rods and cones in the eye to the brain
What is a optic nerve
If there are two dominant traits/ alleles in one parent how can the offspring carry the recessive trait
The other parent has to at least carry one recessive trait for the offspring to be a carrier for that trait
Threadlike structures made of DNA molecules that contain the genes and are found in the nucleus
What are chromosomes
MUCUS - Thick = dominant Soft = recessive
If one parent has TT and the other Tt what percent chance will the offspring have soft mucus
What is 0%
If one parent has O and the other has B what will the offspring have
What is type B
A special type of molecule in our bodies that can do things in our cells[PTC receptors are an example] A molecule made up of a chain of amino acids that performs tasks like sensing stimuli, signaling cells, causing chemical reactions, and regulating our bodies
What are proteins
I one child has straight hair and one has curly hair, and both parents have straight hair how did the one child get curly hair
Curly Hair is recessive
Organelle in cells that contains the genes
What is the nucleus
