d. its genes code for proteins that connect to make blue feathers
d
True or false: If you look more like your dad, it's because you have more genes from you dad.
Provide a 1 sentence explanation for your answer choice.
False. Humans receive 50% of their genes from each parent.
A type of large molecule that performs important functions inside organisms and connects to form your traits
Protein
How many copies do you have of each gene?
Two
A spider is homozygous for silk flexibility. How many different silk flexibility proteins does it have in its cells?
One
This dog has curly fur, but its mother has straight fur. Why does this dog have curly fur? (your answer can be a, b, c, or d)
a. its genes are curly
b. its genes code for proteins which connect to make curly fur
c. it inherited all of its genes from its father
d. it grew up in a different environment from its mother
b.
True or false: The proteins in your cells are determined by what proteins you eat in your environment.
Provide a 1 sentence explanation for your answer choice.
False. Your proteins are determined by your genes
The process in which two parents pass on their genes to create offspring
sexual reproduction
What determines an organisms TRAITS?
Its genes
Two spiders have different parents, but they have the same silk flexibility. How is this possible?
They must have the same silk flexibility gene versions
The wing cells of dragonflies have proteins that connect together. In one dragonfly, the structure of the proteins in the wing cells changed, but the amount of that type of protein in the cell stayed the same.
What happened to the function of that type of protein? (your answer can be a, b, c, or d)
A.The amount of that type of protein stayed the same, so its function doesn’t change.
B.The changed protein connects differently, but its function doesn’t change.
C.The changed protein connects differently, so its function changes.
D.The changed protein connects the same, but its function changes.
C. The changed protein connects differently, so its function changes.
True or false: Two organisms with the same trait will always have the same genotype
Provide a 1 sentence explanation for your answer choice.
gene version or allele
The ________ of a protein determines its function.
structure
Both parents are heterozygous for silk flexibility (F1F2). What are the possible gene combinations for their offspring?
F1F1, F1F2/F2F1, F2F2
Two cats have different parents and they grew up in different environments, but they have the same genes and proteins for fur color. Will they have the same fur color? Explain (1 sentence).
Yes because if they have the same genes, they will have the same proteins/fur color
True or false: If the genes are the recipes, the ribosomes are the croissant baker, the proteins are the recipe book.
Provide a 1 sentence explanation for your answer choice.
False the proteins would be the croissants since ribosomes make proteins and croissant bakers make croissants.
Both scientific ways to describe the genotype of something that can only be seen when two of the same alleles are present
homozygous recessive and purebred recessive
If one parent is heterozygous for black hair and the other is homozygous for white hair, what is the probability 1 of their offspring will have black hair?
50%
V1V2 = venom level (kills)
V2V3 = venom level (stuns)
V1V3 = venom level (kills)
V3V3 = venom level (no venom)
Which gene version is the "most dominant"? Explain.
V1 is the most dominant gene version because when it's paired with any other genotype, the phenotype is venom level (kills).
V3 is the recessive gene because its trait (no venom) is only shown when the genotype is V3V3.
V2 is dominant to V3, but V1 is dominant to both V2 and V3.
There are two wolves that have the same proteins for paw size in their cells. The wolves have different parents. What can you say about the wolves' paw size? Explain.
They will have the same paw size since their proteins for paw size are the same so the proteins will connect in the same way.
True or false: It is possible to have a purebred dominant offspring if one parent is heterozygous and the other is homozygous recessive.
Provide a 1 sentence explanation for your answer choice.
False. There is not an option for a purebred dominant offspring in the punnett square
