What are the two methods animals produce offspring?
Sexual and asexual reproduction
A reproductive process that involves only one parent and produces offspring that are genetically identical to the parent is called
asexual reproduction
What are the two kinds of asexual reproduction?
Fragmentation and budding
What is fragmentation?
a kind of asexual reproduction in which a new organism forms from a piece of the original.
What is budding?
a form of asexual reproduction in which a new animal grows out from the parent until it fully matures and breaks off.
two parents combine their genetic material to produce a new organism which differs from both parents is called
sexual reproduction
What is fertilization?
sexual reproduction involving an egg cell and a sperm cell joining to form a new cell
Where do the offspring's chromosomes come from?
half from father and half from mother
What is a trait?
A specific characteristic that an organism can pass to its offspring through its genes
What are the advantages and disadvantages of asexual reproduction?
Advantage: do not have to find a mate and can produce many offspring quickly. Disadv: They are exact copies of their parents which is a problem if env changes.
What is Inheritance?
the process by which an offspring receives genes from its parents.
What is an allele?
forms of a gene.
If offspring inherited a dominant allele from one parent, the offspring will show
dominant traits
In order for a recessive trait to show,
both parents must pass on the recessive trait
Incomplete dominants results in offspring that are a _____________
Mixture
An example of incomplete dominance
sheep with black fleece and white fleece reproducing resulting in a gray fleece sheep
