Yes, that would be called the Homologous structure, and that changes in natural selection.
no there is no genetic variation for natural selection to act upon
heritable
The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
All the time-all around us. Stronger species survive and the weak are preyed upon and die out.
The individual or his/her (assuming a sexed species) genes. Still a bit of a ' bone of contention in biology between these two levels; the gene and the individual. The only truly marginalized position as to ' target ' of selection is the group.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
No, there is no genetic variation upon which natural selection can operate.
it relies upon the population
no there is no genetic variation for natural selection to act upon
Yes.
heritable
False
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.
all i know is that its False
Vertebrates maintain a specific body shape based upon their skeletons.
New allele combinations are acted upon by natural selection
The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
