asexual
True or False: Asexual is the most complex form of reproduction.
False
What is an animal that produces asexually?
Sponges, corals, certain jellyfish, seastar
What type of asexual reproduction is when a new organism forms from a piece of the parent?
fragmentation
An advantage to this type of reproduction is that there is greater genetic diversity.
sexual reproduction
An advantage to this type of reproduction is that you can produce offspring quickly.
asexual reproduction
What is a sequence of DNA that determines a trait is passed on from parent to offspring?
gene
What is the name for different forms of the same gene?
allele
What is the difference between an allele and a gene?
An allele is a different form of a gene
True or False: In order to show dominant allele, both parents must contribute one to their offspring.
False
When the mixing of colors occurs, this is ______________.
Incomplete dominance
When both alleles are expressed, this is _______________.
Codominance
You have 20,000 alleles. Where did all of your genes come from?
Half the alleles come from the mother and half from the father. This means that both parents contributed at least 20,000 alleles.
What type of inheritance in blood type?
multiple allele
Traits that are controlled by more than one gene are called __________ inheritance.
polygenic
