genetics
whats the difference between meiosis and mitosis
Mitosis is a type of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis produces four genetically unique daughter cells, each with half the number of chromosomes as the parent cell
true of false heterozygous the same
false
a bird has a lang beak is this structural or behavioral adaption
what does GMO stand for
genetically modified organism
whats the difference between archaeology and pathology
the study of evidence for disease in human remains excavated from archaeological sites
what cells are produced from meiosis
gametes
what are genotypes
homozygous dominant, homozygous recessive, and heterozygous
how does genetic drift work
a random change in the frequency of alleles within a population over time
what are the advantages of cloning
to make something better or to keep it the same
what is a fossil
an decomposed remain or an organism
what cells are produced by mitosis
skin cells
what do punnets squares represent
the genes of a new organisms
pepper moths had change of what
mutation
natural selection
genetic drift
B
how does selective breeding work
intentionally choosing organisms with desired traits to breed together, resulting in offspring that are more likely to inherit those desirable characteristics, and repeating this process over multiple generations to enhance the prevalence of the desired traits within a population
why do we study fossils
so we can see what the past was like and how it worked
what types of cells occur when in meiosis
germ cells
Dd is this homozygous or heterozygous
heterozygous
moving due to weather or a certain condition
why do people go to gene therapy
to figure out what diseases or conditions they will have based on genes
what are uses of fossils
to study the evolution of life on Earth, understand past environments and climates, date rock layers, and provide evidence for how continents have shifted over time
what types of cells occur when in mitosis
somatic cells
what is a dominant trait
brown eyes and brown hair
why do organism drift genetically
primarily occurring because of chance events in reproduction, where certain alleles are passed on more frequently than others simply due to random sampling, especially in small populations
what is artificial selection
the process of breeding organisms to enhance specific traits
what is the law of superposition
one of the principles of geology scientists use to determine the relative ages of rock strata, or layers.
