genotype
genotype
Genetic makeup: the genetic makeup of an organism, as opposed to its physical characteristics phenotype
what type of genotype do you have?
Phenotype
Phenotype
visible characteristics of organism: the visible characteristics of an organism resulting from the interaction between its genetic makeup and the environment
everyones phenotype is different.
.
Dominant trait
Dominant trait
a trait that will appear in the offspring if one of the parents contributes it
do you have a dominant trait or a recessive?
genes
genes
…, sequence of DNA that codes for a protein and thus determines a trait
how many genes do you have?
hybrid
hybrid
…, an organism that is the offspring of genetically dissimilar parents or stock
is your pet a hybrid?
purebred
purebred
…, a pedigreed animal of unmixed lineage
my german shephard is a purebred.
alleles
alleles
…, different forms of a gene
what color are your alleles?
heterozygous trait
heterozygous trait
…, a mixed pair of alleles on homologous chromosomes for any given trait
do you have a hetrozygous trait like i do?
homozygous trait
homozygous trait
…, an identical pair of alleles on homologous chromosomes for any given trait
no, mine are homozygous.
characteristic
…, a distinguishing quality
you have very interesting characteristics.
probablity
probablity
…, A number that describes how likely it is that an event will occur.
what is the probablity of you dieng at a young age?
DNA
DNA
…, deoxyribonucleic acid, the material that contains the information that determines inherited characteristics
everyones DNA is different.
punnett square
…, A device used to figure out possible genotypes of offspring. (2 wds, no spaces)
have you ever used a punnet square?
meiosis
meiosis
(genetics) cell division that produces reproductive cells in sexually reproducing organisms
were you born through meiosis?
asexual reproduction
asexual reproduction
process by which a single parent reproduces by itself
plants reproduce by using asexual reproduction.
binary fission
binary fission
a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
binary fission seems weird to me.
budding
budding
reproduction of some unicellular organisms (such as yeasts) by growth and specialization followed by the separation by constriction of a part of the parent
budding is a very interesting way to reproduce.
sexual reproduction
sexual reproduction
process by which cells from two different parents unite to produce the first cell of a new organism
lots of rumans use sexual reproduction to have kids.
sex chrmosomes
sex chrmosomes
chromosomes that determine the sex of an organism
each parent has 23 sex chromosomes
sex linked disorders
dieseases that are determined by genes found on the sex chromosomes. particularly the X chromosome
do you have any sex linked disorders ?
pedigree
pedigree
ancestry of a purebred animal
i looked up the pedigree of my dog.
genetic counseling
genetic counseling
the process of informing a person or couple about their genetic makeup
my mom and dad used genetic counseling.
selective breeding
selective breeding
The process of selecting a few organisms with desired traits to serve as parents of the next generation
many people use selective breeding for their animals.
incomplete dominance
one allele is not completely dominant over the other allele
i bet everyone has incomplete dominance.
multiple alleles
multiple alleles
three or more forms of a gene that code for a single trait
everyone has multiple alleles.
nucleotide
nucleotide
in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base
mutation
mutation
a change or alteration in form or qualities
lots of animlas change through mutation.
RNA
RNA
(biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes
RNA is really different from DNA
genetic engerneering
genetic engerneering
inserts a gene from one organism into the DNA of a different organism
genetic engeering is a great way to determine DNA
sterm cells
sterm cells
unspecialized cells that can develop into specialized cells when under the right confitions
sterm cells are very important cells.
