When you cross two dissimilar traits it is called?
Terms in this set (20) A cross between dissimilar individuals to bring together their best characterisitcs is called. hybridization. crossing individuals with similar characterisitics so that those characteristics will appear in the offspring is called. inbreeding.
What is the crossing of dissimilar individuals to bring together of both organisms?
Chapter 13: Genetic Engineering
| A | B |
|---|---|
| Hybridization | the breeding technique that involves crossing dissimilar individuals to bring together the best traits of both organisms |
| Inbreeding | the continued breeding of individuals with similar characteristics |
| Polyploid | having many sets of chromosomes |
Which term is used to describe DNA from two different species?
DNA molecules produced by splicing together two or more DNA fragments are called recombinant DNA molecules; they have made possible many new types of cell-biological studies.
Which of the following joins two pieces of DNA together?
The ligase joins the two fragments of DNA to form a longer strand of DNA by “pasting” them together.
What method in genetics is used to cross between two individuals that are both heterozygous for two different traits?
Incomplete dominance
Incomplete dominance is the expression of two contrasting alleles such that the individual displays an intermediate phenotype. Codominance is a variation on incomplete dominance in which both alleles for the same characteristic are simultaneously expressed in the heterozygote.
What is a genetic cross called between an individual of unknown genotype and a homozygous recessive?
In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).
What is breeding of dissimilar individuals?
What is Hybridization? crossing dissimilar individuals to bring together the best of both organisms. The continued breeding of individuals with similar characteristics because of this, there is always a chance that a cross between two individual will bring together two recessive alleles for a genetic defect.
What is the result of DNA ligase’s action?
What is the result of DNA ligase’s action? DNA is broken up at specific sites. DNA translation occurs. A daughter strand of DNA produced during chromosome replication can be composed of leading and lagging strands from different replication bubbles.
How does the DNA from two different organisms combine group of answer choices?
Joining DNA molecules from two different organisms results in what is called recombinant DNA. This process is possible because there are enzymes that can cut the DNA of both organisms in a way that allows any DNA with similar cut ends to stick together.
Which enzyme join DNA molecules together?
DNA ligase
DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA.
Which two types of DNA transfer are commonly used in genetic engineering?
The ability to alter an organism’s genotype relies on the introduction and persistence of foreign DNA, also known as transgenic DNA. Transgenic DNA can be dichotomized into two types: (1) natural (from another organism) or (2) recombinant (i.e., synthesized cDNA).
