Why is corn fertilized in the lab so useful when analyzing dihybrid crosses?
Givemetheanswersplea...
Because in field conditions corn (maize) is cross pollinated. Under laboratory conditions, it is made homozygous by repeated self-pollination for at least 5 generation to attain 99 % homozygosity. The homozygous parents when crossed will show independent assortment of alleles.
In lab, one can predetermine the genotypes you want to cross with.

DNA fingerprinting is used to identify individuals by?
analyzing unique patterns in their DNA, such as short tandem repeats (STRs). By comparing these patterns between samples, scientists can determine the likelihood of a match, which is useful in forensic investigations, paternity testing, and identifying genetic diseases.
How do you use a Punnett Square and what do they do?
A Punnett Square is a tool used to predict the ratio of genotypes and phenotypes in offspring based on the genetic traits of the parents. It helps to illustrate the possible combinations of genes that can result from a genetic cross between two individuals. By filling in the squares with the parents' alleles, you can determine the probability of different outcomes in the offspring.
Which genetic engineering branch is most useful for the goal of supplying evidence in court?
Forensic genetics is the branch of genetic engineering most useful for supplying evidence in court. It involves analyzing DNA samples to establish biological relationships, identify individuals, and determine the source of biological evidence found at a crime scene.
What is seismic profilling useful for?
Seismic profiling is useful for identifying subsurface structures and characteristics by analyzing the reflection and refraction of seismic waves. It helps in locating potential oil, gas, and mineral deposits, as well as understanding the geology of an area for engineering and construction purposes. Seismic profiling is also used in assessing seismic hazards and risks for earthquake-prone regions.
Is analyzing web statistics ethical?

Why is the law of conservation of momentum useful in analyzing the collision between two bodies?
The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.

What does pitch wave mean?
A pitch wave is a waveform that represents the frequency or pitch of a sound. It shows how the pitch changes over time in a graphical form. This is useful in analyzing and synthesizing audio signals.
Which resource is likely to be most useful in analyzing the choice of diction in the play Beowulf an epic written around AD 700?
A scholarly article or book that focuses on Old English literature and language would be the most useful resource for analyzing the choice of diction in the epic poem Beowulf. Look for sources that provide historical context and linguistic analysis of Old English vocabulary and syntax to better understand the diction used by the anonymous poet of Beowulf.
