what is the difference between a dominant & recessive gene?
Not gonna lie, this answer should be kind of obvious
through what process do zygotes divide?
mitosis
There are no questions left so, uh... name to four bases of DNA
adenine (A), cytosine (C), guanine (G), and thymine (T)
What is the longest stage in the cell cycle
Interphase
what are homeotic genes?
genes that regulate the development of an anatomical structure
what is a gamete?
haploid reproductive cell
how many sets of chromosomes do humans have?
23
what is one of the two halves of a chromosome called?
Chromatids
what are the three stages of the cell cycle
Interphase, Mitosis, Cytokinesis
through what process are haploid gametes made from diploid?
meiosis
what does diploid mean?
something about homologous pairs of chromosomes
what is the difference between genotype and phenotype
one is the physical appearance, one is the genetic makeup, as for which one is which you should know
what is the centromere?
the binding point of two chromatids
there are like zero questions left... so what is the third phase of mitosis?
anaphase
what is codominance?
different alleles being expressed at the same time
what is a haploid cell?
they have one set of chromosomes
What animal's fur changes color depending on temperature?
like all of them do, but I am looking for the Himalayan rabbit
how many sets of autosomes do we meat popsicles have?
22
name a phase of mitosis, I guess...
You should know this
What are Mendel's three genetic principles?
Heredity, Segregation, Independent assortment
what is the basis of asexual reproduction?
mitosis
explain one of Mendel's genetic principles in detail
Heredity- when two different alleles are present for a trait, one is dominant and its trait is expressed; the other is recessive and is hidden unless both alleles are recessive.
Segregation-Each organism carries two alleles for a trait. These alleles separate during the formation of gametes, so each gamete carries only one allele for each trait.
Independent assortment- Genes for different traits are passed on independently of one another during gamete formation, if they are on different chromosomes or far apart on the same chromosome.
what is a mutation?
a random change in the replication of bases
what are the four phases of mitosis... in order
prophase, metaphase, anaphase, telophase
How can an organism's environment affect its phenotype?
things such as temperature can change the color of an animal's fur.
