No
100
Why is this bird blue?
a. its genes are blue
b. it is homozygous
c. it eats blue food
d. its genes code for proteins that connect to make blue feathers
d. its genes code for proteins that connect to make blue feathers
100
True or false: Most organisms inherit more copies of a gene from one parent than the other. Why?
False. Organisms inherit one copy from mom and one copy from dad
200
A type of large molecule that performs important functions inside organisms
Protein
200
How many copies do you have of each gene?
Two
200

One
200

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

200
True or false: The traits are determined by what by the environment you live in? explain
False. Your traits are determined by your protiens
300
The Characteristics that all members of species have.
Feature
300
What determines an organisms TRAITS?
Its protein molecules
300
Two spiders have different parents, but they have the same silk flexibility. How is this possible?
They must have the same silk flexibility proteins
300
Why does silk flexibility vary?
Different protein molecules within an individual's cells lead to different traits
300
True/ False: There are two genes for each trait, and they are always identical
False
400
A specific form of a gene that provides instructions for making a particular protein molecule ( small part of the gene)
gene version/ Allele
400
What determines the function of a protein molecule?
Its structure and how it connects to other protein molecules
400
Both parents are heterozygous for silk flexibility (F1F2). What are the possible gene combinations for their offspring?
F1F1, F1F2, F2F2
400

Yes!
400
True or False: Dominant traits always hidden behind recessive traits.
False.

Why do siblings and parents differ from each other?
Offspring inherit different combinations of gene versions ( alleles) from parents.
