The passage of genetic instructions (traits) from parent to offspring.
100
Any trait of an organism that enhances its chances of surviving and reproducing in its environment
Adaptation
100
Are structures that contain hereditary info & transfer it to the next generation; the occur in nearly identical pairs in the nucleus of every cell
Chromosomes
100
Any close relationship between species.
symbiosis
200
Where are genes located?
In the chromosomes
200
Who first studied heredity and the passage of traits from one generation to the next?
Gregor Mendel
200
trout's ability to extract oxygen from water, the bee's ability to transform nectar into honey, humans ability to reason are examples of: structural, functional, or behavioral adaptation?
stuctural
200
The 2 _________ on paired chromosomes constitute a gene. Also they are variations of genes that determine traits.
Alleles
200
A symbiotic relationship between species where both are benefited and give example.
mutualism

What are the threadlike structures of DNA that carry genes called?
Chromosomes
300
What type of organism did Gregor Mendel use to first study heredity?
Pea Plants
300
A squirrel's propensity for storing nuts, a bears long winter hibernation are examples of: structural, functional, or behavioral adaptation?
Behavioral Adaptation
300
__________ alleles exhibit their effect if they are present on 1 chromosome
Dominant allele
300
A symbiotic relationship between species where 1 benefits & the other is not helped or harmed.
Commensialism

The physical trait observed in an offspring is known as it's -
Phenotype
400
A hawk's talons, the shark's broad tail, the clam's hard shell are examples of: structural, functional, or behavioral adaptation?
Structural adaptation
400
________ alleles exhibit their effect only when both chromosomes have the allele.
recessive allele
400
A symbiotic relationship between species where 1 benefits & the other is harmed.
Parasitism
500

Variation

Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
