This trait is developed later in life:
acquired
inherited
mutated
What is an allele?
a cell that contains two sets of chromosomes, one from each parent
twisted “ladder” shape of DNA
different forms of a gene
What is a chromosome?
the passing of traits from parent to offspring
thread-like structures within the nucleus that are made up of DNA
passed down from parent to offspring
DNA is:
a nucleic acid that passes from parent to child in the form of a chemical code
a trait that will always show up in the organism if the allele is present
the scientific study of heredity
A dominant trait is:
sections of DNA that control specific traits
passed down from parent to offspring
a trait that will always show up in the organism if the allele is present
The scientific study of heredity is called:
genetics
DNA
traits
A genotype is:
passed down from parent to offspring
the combination of alleles an organism inherits
a permanent change in the genetic code
What is heredity?
a permanent change in the genetic code
the likelihood or chance of something happening
the passing of traits from parent to offspring
Heterozygous is:
a genotype that has two identical alleles for the same gene
a genotype that has two different alleles for the same gene
a permanent change in the genetic code
Homozygous is:
a genotype that has two identical alleles for the same gene
a genotype that has two different alleles for the same gene
a trait that is controlled by multiple genes
An inherited trait is:
acquired by study or repetition
developed later in life
passed down from parent to offspring
A learned trait is:
acquired by study or repetition
developed later in life
passed down from parent to offspring
What is a mutation?
a permanent change in the genetic code
a trait that is controlled by multiple genes
the likelihood or chance of something happening
Traits influenced by nature are impacted by:
environmental factors
genetic factors
multiple genes
Trait influenced by nurture are impacted by:
environmental factors
genetic factors
multiple genes
What is a phenotype?
the visible traits an organism exibits based on the alleles it inherits
the process of DNA duplication
to multiply or make more of something
In the punnett square below, what belongs in the missing square
What is a recessive trait?
to multiply or make more of something
a trait that will always show up in the organism if the allele is present
a trait that will always be hidden if the dominant allele is present
A trait is:
physical characteristics of an organism
a permanent change in the genetic code
passed down from parent to offspring
A phenotype is:
The genetic make up (code)
The physical trait
