Genetics Vocab
The passing of traits from parents to offspring.
What is heredity?
A type of reproduction that gives genetic variation to its offspring.
What is sexual reproduction?
Genotye: BB
What is homozygous dominant?
This type of asexual reproduction occurs when the parent organism splits in two, producing two daughter cells identical to the parent cell. Bacteria reproduce this way.
What is binary fission?
Happens slowly.
What is a disadvantage of sexual reproduction?
The pair of letters that represent forms of a gene.
What is genotype?
A type of reproduction that allows a large part of the population to die off due to changes in the environment.
What is asexual reproduction?
Genotype: nn
What is homozygous recessive?
This type of reproduction occurs when specialized cells, made by one parent, are carried through the wind, to a place where they can grow. Ex: Fungi and Green Algae
What is spore formation?
Produces a small number of offspring.
What is a disadvantage of sexual reproduction?
The physical description of a trait. Example: Brown hair, Blonde Hair
What is a phenotype?
A type of reproduction that requires complex structures and allows the organisms to live longer to raise their offspring.
What is sexual reproduction?
A black cat (BB) is crossed with a white cat (WW). All of their offspring are gray (BW). This is an example of:
What is incomplete dominance?
This type of asexual reproduction occurs when a single parent breaks into parts that develop into whole new individuals. Example: Sea Stars, Flatworms
What is fragmentation?
Helpful or beneficial traits are passed down.
What is an advantage of asexual reproduction?
Creates body cells
What is mitosis?
A type of reproduction whose function is to make more cells or grow/repair cells
What is asexual reproduction?
A black chicken (BB) is crossed with a erminette chicken (BW). What percentage of offspring will be black?
What is 50%?
This type of asexual reproduction occurs in strawberries and potatoes. It does not involve seeds. New plants grow from the offshoots of the parent plant.
What is vegetative reproduction?
Genetic variation-gives a better chance of survival.
What is an advantage of sexual reproduction?
A person who has the trait on only one chromosome and does not express the trait. Example: Queen Victoria and hemophilia, a blood-clotting disorder
What is a carrier?
A type of reproduction that allows ALL offspring to reproduce
What is asexual reproduction?
Both genes are dominant, and the offspring shows genes from both parents.
What is codominance?
This type of reproduction occurs when an individual forms from an outgrowth of the parent. Ex: Yeast and Hydra
What is budding?
They only need one parent to reproduce, so they don't need to find a mate.
What is an advantage of asexual reproduction?
