History
________________________ is the study of heredity
Genetics
_______________ are different traits in a gene or chromosome) they can be dominant or recessive
Allele
____________ cell division produces different offspring while Mitosis (mitotic) cell division produces _________copies of new cells or offspring
EXACT
Genotype or Phenotype-
The __________________________ determines the way something looks or it's ________________.
Genotype
Phenotype
Alleles can be dominant or _________________, and create an organisms genotype and ____________________ (hint: how it looks)
recessive
phenotype
Gregor Mendel is the _________________ of genetics
father
__________________ organisms have the same alleles for example BB, bb
Homozygous
RR, TT, DD, rr, gg are examples of ______________ (heterozygous or homozygous) traits
While Rr, Dd, Rr and Gg are examples of __________________(heterozygous or homozygous) traits
Homozygous
Sexual reproduction involves both _________ and _______________ parents
male---female
Dominant
A ________________ square is used to predict what kind of traits (alleles) offspring will have.
Punnet
________________ are little recipes of who we are
Chromosomes
_______________________ traits are traits (characteristics) that seem to disappear or even skip a generation--Like left handedness, blonde hair
Recessive
An organism's _______________ is the way it looks.
phenotype
In sexual reproduction, chromosomes from both parents combine to produce the offspring which can help a species' ____________________
survival--survivability
An organisms _________________ is it's DNA code for a trait. You can not see it, but you can see the organism's phenotype
genotype
__________________ are portions of chromosomes that hold specific traits that we get from our parents
Genes
___________________________ hold the genetic information for an organism and are located in the _____________ of every cell
Chromosomes
nucleus
In asexual reproduction, the offspring is __________________ because it does not share different chromosomes
identical---exact
___________________________ hold the genetic information for an organism and are located in the _____________ of every cell
Chromosomes
Nucleus
________________________ selection is when humans pick out what characteristics they want from an organism and bred it.
Artificial
What are the names of the 2 chromosomes that determine our gender
X and Y
Sexual reproduction involves_________________ (type of cell division)
meiosis
Heterozygous have __________________ alleles-Bb, Rr
different
Asexual reproduction uses ________________ cell division because the offspring are EXACT copies.
