Spiders
True or false: spiders get their protein molecules for silk flexibility by eating them
False, spiders get their protein molecules for silk flexibility from their parents.
True or false: everyone has the same proteins
False because we have different parents
True or false: if two people do not look alike, there is no way they are twins
False, twins do not always look the same
True or false: twins can have different parents
It is common for puppies to be born with lots of twins. Are these fraternal or identical?
They are fraternal
Are all spider silks the same?
Yes or no
No, because they get different proteins from their parents
If my mom has blue eyes and my dad has brown eyes, are my traits for eye color heterozygous or homozygous
Heterozygous because blue and brown are different traits
True or false: there is a gene to determine if we like sports
False because genes do not determine personality. Genes determine what you look like and how healthy you are.
True or false: there is only one kind of twin
False, there are two kinds of twins
The mother cat has a long tail and the father cat has a short tail. Will it be possible for there to be a kitten with a medium tail?
Yes it could be possible if their proteins connected that way
Where do spiders get their genetic proteins from?
Their parents
What does heterozygous mean?
Heterozygous means that there are two sets of instructions for a trait (brown eyes, blue eyes)
True or false: people can change their genes at any time
False, people cannot change their genes willingly
True or false: a fraternal twin happens when the egg divides itself
False, fraternal twins happen when there is a tie between sperm
The mom giraffe has a long neck, the dad giraffe has a short neck, and the oldest baby has a medium neck. Will all the rest of the babies have medium necks?
No, they could have tall, short, or medium
True or false: If both spider parents have strong silk, will the babies have strong silk?
False, because they could have different genes from their grandparents.
What does homozygous mean?
Homozygous means there are two copies of the same instructions for a trait (brown eyes, brown eyes)
True or false: if two parents have the same color eyes, their child will not be able to have different colors of eyes
False because we carry the genes from our parents with us and they can be passed on as well as the expressed gene
True or false: identical twins can be of different genders
False, they have to be the same gender because they came from the same fertilized egg
The S came from mom and the M came from dad, SM means short feathers.
Why do traits for silk flexibility vary within Darwin’s bark spiders?
The traits for silk flexibility vary in Darwin's bark spiders because they get two copies of proteins, one from their mom and one from their dad. Spiders can have stretchy silk or weak silk or stong silk.
True or false: If you change the protein in a cows gene then you can change the milk
True because some cow's milk can be good and some can bad and some might be better at making cheese than others.
True or false: it takes two copies of the CF gene for someone to have cystic fibrosis
True, if they only have one copy they are known as a carrier
True or false: there is only one way for there to be triplets.
False, there are two ways to get triplets, identically and fraternally
The mom chicken has white feathers (WhR) and the dad has red feathers (RY.) What are the possible combinations the babies could get?
WhR, WhY, RR, RY.
