In this type of asexual reproduction seen in the hydra, the offspring grows directly from the parent and then pinches off when developed enough to survive on its own. This type of asexual reproduction is known as _____.
Fragmentation
Budding
Regeneration
Vegetative Propagation
Which definition matches the term chromosome?
A long string of coiled up DNA containing many many genes.
A molecule that passes on hereditary information
Instructions to make one trait or protein
None of these
A gene for a specific trait does not have a specific location on a gene. (In other words, it does not matter where a gene is located, as long as it is on the chromosome.)
True
False
Select all that apply. One of the greatest advantages of sexual reproduction when compared to asexual reproduction is that in sexual reproduction
genetic diversity is created!
many offspring can be created in a short amount of time.
less energy is required.
no mate is needed.
True of False. Asexual reproduction only requires one parent while sexual reproduction typically requires two parents.
True
False
Select all that apply. A mutation
is a change in DNA, or instructions to make a protein.
can be caused by the environment.
can be caused by inherited genetics.
is always detrimental to (bad for) the organism
Select all that apply. Some things I must do to do my best on today's assessment is to
Follow CHAMPS.
Respect myself and my classmates.
Raise my hand for help.
Exhibit PRIDE
In a class assignment studying heredity and genetics students rolled a dice to choose which trait was inherited. In this activity, the roll of the dice represented
how an organism chooses the traits it wants to inherit.
how traits are inherited in a random way.
the inheritance of traits are planned.
how parents can choose traits for their kids to inherit.
True or False. All humans have 23 pairs of genes in their somatic cells. (Remember: Somatic cells include all cells except sex cells!)
True
False
Sometimes the ________ inherited from each ___________ look the same, and sometimes they look different.
chromosomes, genes
parents, chromosome
genes, offspring
genes, parent
Turkey farmers have noticed that every once in a while, a female turkey will produce viable eggs (eggs that will survive) when no male is present. The eggs often results in poults (chicks) that are sick and nearly always male. This is an example of
asexual reproduction
sexual reproduction
both
neither
Select all that apply. Sexual reproduction requires (needs)
fertilization.
gametes.
typically one parent.
typically two parents.
Sex cells include egg and sperm. Another name for a sex cell is a
neuron.
gamete.
somatic cell
autonomic cell.
Parents look like their offspring because parents inherit their DNA (and traits) from their offspring.
True
False
Select the correct hierarchy (order) from smallest (micro) to largest (macro).
__________ -> __________ -> __________ -> __________
Trait, Chromosome, gene, DNA
Chromosome, gene, trait, DNA
DNA, Chromosome, Gene, Trait
DNA, Gene, Chromosome, Trait
Advantages of asexual reproduction include
many clones/offspring can be produced in a short amount of time.
that succeeds best in a NON-changing environment.
it produces the greatest amount of genetic diversity!
it does not require finding a mate.
A mutation is
a change in the instructions in DNA.
is always a bad thing for an organism.
may or may not affect the production of a trait.
a source of genetic diversity that can influence evolution.
Melanin is a protein that influences the trait of
speed.
size.
pigmentation.
digestion.
Select the BEST answer. The study of the passing of traits from parent to offspring is called
Metabolism
Heredity
Genetics
Evolution
In __________ reproduction, _____________ occurs when egg, and sperm, or _________, unite (come together)
Sexual, Fertilization, gamete cells
Asexual, Fertilization, somatic cells
Sexual, Cell division, gamete cells
Asexual, Cell division, somatic cells
