Specific characteristic that organism can pass to its offspring in its genes
trait
allele
variation
fertilization
Asexual reproduction is different from sexual because
offspring are identical to parents
offspring only have 1/2 the chromosomes from parents
have no genetic material
have more variety in their traits
Why do different offspring of the same parent usually look different when it is sexual reproduction?
offspring receive no genetic material
offspring receive half the amount of chromosomes
offspring receive all of the chromosomes
offspring are cloned
Which trait will be expressed when you have only one allele?
recessive trait
dominant trait
What could be a possible benefit / advantage to an organism expresses codominance or incomplete dominance traits
offspring are the same and it increases survival
offspring have little variations
genetic diversity decreases
offspring have lots of variation & increase its survival
A new organism grows identically from a fallen part of the parent
fragmentation
fission
budding
fertilization
Reproduction involving 2 parents that combine their genes to produce offspring different from parents is asexual
True
False
The process by which an offspring receives genes from its parents
fertilization
alleles
genes
inheritance
A type of reproduction allows for variation and increase survival rate is known as
sexual reproduction
asexual reproduction
These organisms reproduce without a mate and can have lots of offspring in short amount of time...
sexual
asexual
These are different forms of the gene which you need at least two of to form a trait is...
trait
allele
gene
These traits can be affected by your experience
complete dominance
Incomplete dominance
acquired
recessive trait
This type of inheritance is influenced by more than one gene
incomplete dominance
polygenetic inheritance
complete dominance
recessive
