The passing of traits from parent to child is the basis of heredity
Check all that are true regarding traits:
Our genes encode the instructions that make our traits
Genes are made of DNA
Genes resides in the chromosomes
A child gets 46 chromosomes from each parent
When the egg and sperm cell join together, what do they initially form?
a monkey
a baby
a zygote
Characteristics of one's physical make up are ______________________ (select all that apply)

Traits are defined only by genes
The environment or non-genetic factors can change traits
Alleles are the set of genetic information for a trait
Single gene traits are _____________________ (select one or more answers)

Having two of the same allele for a trait is called _______________________________

Having two different alleles for a trait is called _______________________________
red flower plus white flower equals pink flower is an example of incomplete dominance.
The dominant allele is masked when it appears with a recessive allele
Alleles are one of a number of different forms of a gene
The specific location ("address") on a chromosome of a particular gene code for making a certain protein is _____________
gene
locus
DNA
The sequence of nucleotides that codes the making of a specific protein
allele
ribosomes
The genotype for a given trait is made up of a combination of alleles inherited from parents
A change in the nucleotide order of a gene which makes a new allele is a mutation
blue eyes are recessive.
The phenotype of blue eyes only occurs if the genotype has two recessive alleles.
If the genetics of something is complex, it typically means that there are many different loci that play a role.
