Hormones/Plant Responses
This hormone is produced in shoot tips and is
responsible for apical dominance in plants.
Auxin
After meiosis, how many daughter cells result?
four haploid daughter cells
What is heredity?
the passing of genes from one's parents to offspring
Individuals best suited to compete, survive, and reproduce in their environment will pass on favorable traits.
What is Natural Selection?
A plant that is growing towards the sun is showing this.
Positive phototropism
A tetrad can be observed during this stage of meiosis.
Prophase 1
An individual's observable traits are referred to as this.
Phenotype
Evolution happens to ____________ not ______________.
Populations/Species
This hormone promotes cell division and
releases lateral buds from apical dominance.
Cytokinin
What is fertilization?
Process in sexual reproduction in which male and female reproductive cells join to form a zygote
An individual who is heterozygous for a
particular trait, yet expresses both alleles
of that trait, is said to show this.
Incomplete dominance
The more alike two
different organisms are, the
more recently they shared a
__________ ___________.
Answer: Common
The more alike two different organisms are, the more recently they shared this.
Common ancestor
This hormone promotes fruit ripening.
Ethylene
This stage of meiosis is identical to mitosis.
In a monohybrid cross between two heterozygous parents, what percentage of their offspring is expected to have the recessive trait?
25%
Darwin observed that all sexually reproducing populations have this.
Genetic variation.
The internal 24-hour clock found in all eukaryotes.
Circadian rhythms.
An alternation of generation/sporic meiosis
In addition to genetics, what other factors can influence how an organism grows and develops?
Environmental factors
What is the most compelling (and modern) line of evidence that demonstrates evolutionary relationships?
What are DNA Sequences/Protein Sequences?
