Mitosis and Meiosis
During this stage of mitosis, chromosomes line up in the middle of the cell.
Metaphase
Salt (NaCl) is an example of this type of substance because it is made of two elements chemically bonded together.
compound
When a red flower and a white flower produce pink offspring, this type of inheritance is occurring.
Incomplete dominance
This type of cell division produces gametes with half the number of chromosomes as the parent cell.
Meiosis
This is why meiosis is important for sexual reproduction and genetic diversity.
It creates genetically different cells
This property describes a substance’s ability to react with another substance to form something new.
Chemical property
Two parents are heterozygous for an incompletely dominant trait. This percentage of their offspring is expected to show the blended phenotype.
50%
This term describes two alleles that are different for the same trait.
Heterozygous
This type of cell division helps your body grow and heal cuts.
Mitosis
Milk is considered this type of mixture because its particles are evenly distributed but not chemically bonded.
Homogeneous mixture
If a red flower (RR) and a white flower (WW) show incomplete dominance, what phenotype would all offspring have?
Pink
This phase of mitosis is when the chromosomes condense and become visible under a microscope.
Prophase
In mitosis, this structure pulls chromosomes apart to opposite sides of the cell.
Spindle fibers
When a glow stick is snapped and begins to glow, this type of change has occurred because energy is released and new substances form.
Chemical change
A mother has blood type AB and the father has blood type O. What are the possible blood types of their children?
Types A and B
During meiosis, homologous chromosomes separate in this stage.
Anaphase I
This event during meiosis helps create genetic diversity by exchanging DNA between homologous chromosomes.
Crossing over
Two samples look identical. Sample A is made of only one type of atom. Sample B is made of two different atoms chemically bonded in a fixed ratio. Neither sample can be separated by physical means. Based on this information, how should each sample be classified?
Sample A is an element
Sample B is a compound
A cow with black-and-white spotted fur (BW) is crossed with another cow that is also black-and-white spotted (BW). In codominance, what fraction of their calves are expected to show both black and white spots?
50%
Mixing sand and sugar produces a mixture in which the components can be separated physically. This type of mixture is called what?
Heterogeneous mixture
