What does heritable variation mean?
Inherited variation is when we inherit half of our characteristics from each parent.
What evidence lead scientist to think that green algae were the ancestors of plants?
they have the same photosynthetic pigments.
What information does a scientist use to determine an organisms phylogeny?
A scientists uses an organisms genetic and shared physical traits.
How do the embryos of different species support the theory of evolution?
The morphology of embryos at various stages, and even the developmental patterns of embryos, show the same pattern of nested hierarchies that we find in morphology, behaviour and genomes, independently confirming common descent, but also teaching us how morphologies could diverge through relatively minor genetic shuffling.
Which of the processes below is a way scientist can accelerate the process of traditional crossbreeding through inserting beneficial traits in the DNA of a plant?
by planting desirable genes in the DNA through genetic engineering
Why do scientist today rely on molecular and genetic similarities to classify organisms?
Because it is more accurate than using physiological differences as used in the past.
What can be determined by studying genetic similarities between two species?
Genetic courses of behavior can be determined by studying genetic similarities between two species.
What is the genetic composition determining a trait?
Genotype is the genetic makeup of a trait.
How can we determine how closely related two species are?
There are many methods to determine how closely related two species may be. You could begin by comparing embryo morphology, doing radioactive dating or a visual inspection of structural and genetic similarities.
Who would have the most genetic similarities identical twins or fraternal twins?
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
What are the similarities of eukaryote prokaryote and viruses?
They all contain DNA in there genetic material
What kind of technique do scientist use to make transgenic organism?
Genetic Engineering.
What similarities and differences could you look at when you classify organisms?
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities
What are the similarities of viruses and prokaryotes?
They all contain DNA in there genetic material
What is the name of the profession that carries out preimplantation genetic diagnosis?
doctor-scientist specialist/Laboratory Scientist Doctors
A scientist makes an educated guess that diabetes is caused by genetic factors His guess is an example of a n?
A scientist making an educated guess that diabetes is caused by genetic factors is stating a hypothesis. The scientist may then design an experiment to test this hypothesis.
What Carrys the genetic code and determining an organism's structure and function are the functions of .?
proteins
