Living Things and Cells
A characteristic shared by all living things
What is reproduction, grow and develop, get and use energy, respond to the environment, or maintain homeostasis?
This type of reproduction results in identical offspring which are identical to the parent
What is asexual reproduction?
This is the type of cell division that produces body cells for growth, development, and replacement of dead or damaged cells.
What is MITOSIS?
These are the different forms of a gene for a trait.
What are alleles?
A trait that is only expressed if there is no dominant trait present.
What is a RECESSIVE trait?
An organelle that plant cells have and animal cells do not
What is chloroplasts or cell wall?
This is the number of parents required for asexual reproduction
What is 1?
Number of chromosomes found in a cell of a human body cell (with 46 chromosomes) after it divides by mitosis.
What is 46?
This is the code for the two alleles an organism has for a particular trait.
What is a genotype?
The genotype a person would have for blue eyes, if blue eyes is a recessive trait (b) and Brown eyes is dominant (B)
What is bb?
This is the organelle where you would find the genetic material in a cell.
What is the nucleus?
This is the type of asexual reproduction in which a cell divides into two equal sized daughter cells.
What is binary fission?
What is MEIOSIS?
This is the physical appearance of a trait
What is a phenotype?
The genotype a person would have if they were heterozygous for brown eyes.
What is Bb?
This type of cell has no nucleus.
What is a bacteria (or prokaryotic) cell?
This type of asexual reproduction found in yeast cells happens when a small offspring begins to grow off of the parent, gradually gets bigger and then divides away from the parent.
What is budding?
What is 23?
A trait that is always expressed in a phenotype if it is present in the genotype -- only one allele is needed to create this trait
What is a DOMINANT trait?
Used to predict the possible genotypes and phenotypes of the offspring of a particular set of parents.
What is a Punnett Square?
This organelle is the part of the cells that allows substances to enter and leave the cell.
What is the cell membrane?
This is one advantage to organisms that reproduce asexually.
What is -- they can create many offspring quickly and don't have to find a second parent?
The number of chromosomes found in a sperm cell in the pollen of a peanut plant that normally has 40 chromosomes in a body cell.
What is 20?
A genotype with two different alleles for the trait.
What is HETEROZYGOUS?
The Father of Modern Genetics
Who is Gregor Mendel?
