Punnett Square...... I'm in 7th grade and know that.
Punnet Squre is where you find breeding

The second generation phenotypes resulting from the cross of true-breeding monohybrid pollination will display a ratio of?
1:4
How does meiosis accounts for recombinant phenotypes?
recombinants are formed in prophase I because that is when crossing over occurs. Crossing over brings the alleles together into new combinations, switching two traits but not all of them. Then in the following steps of meiosis the recombinants are distributed into different gametes, resulting into recombinant phenotypes.
How do you create a hybrid plant?
You cross-pollinate two different varieties and the resulting offspring are hybrids. Of the same species.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be what?
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be 9:3:3:1. This ratio is obtained when two heterozygous individuals are crossed for two traits that are independently inherited. The ratio represents the different combinations of phenotypes that can arise from the cross.
What is the main metal of stainless steel?
Primarily iron, with some carbon and nickel in the alloy. The precise proportions will determine the properties of the resulting steel.
What blood type would A and AB make?
If the first person is AA, then the possible resulting genotypes are AA or AB. If the first person is AO, then the possible resulting genotypes are AA, AB or BO.
When is a binomial distribution cumulative?
It is cumulative when you add together the probabilities of all events resulting in the given number or fewer successes.

Does a punnet square show the actual results of a genetic cross?
A Punnett square is used to determine an idealized outcome. For example, all possible combinations of genotypes of the gametes are represented, as if they had been actually been produced. The proportions of the various resulting genotypes are also idealized. In actual crosses, the numbers will vary from the idealized numbers due to chance.
Why do repeated applications of single drug or pesticide result in resistance among bacterial strains and species of insects?
Repeated applications of drugs/pesticides result in resistance by way of natural selection. In any given population of organisms individual genetics will vary with varying degree expressed in their genotype. These variations result in phenotypic expression. Certain phenotypes will be more or less resistant to particular drugs/pesticides. Survival of the fittest. This is particulary important with organisms which have a fast reproductive cycle like bacteria and insects. This selecting for fitter individuals results in a population developing resistance. The ones suseptible to drugs/pest will die off leaving resistant ones. Over repated exposure and generations new genotypes with new phenotypes evolve resulting in "super bugs".
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be what?
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be 9:3:3:1. This ratio is obtained when two heterozygous individuals are crossed for two traits that are independently inherited. The ratio represents the different combinations of phenotypes that can arise from the cross.
What is the difference between 'stochastic' and 'probabilistic'?
I think most people use them as synonyms. In general usage, it can be appropriate. However, a probabilistic approach describes the occurrence of deterministic states with given probabilities, while stochastic processes are built up by sequential steps occurring with given probabilities. Think of the difference between throwing a die once which determines the state you will arrive at and throwing a die multiple times where the resulting states are (can be) dependent on the previous states.
What is the purpose of an atom smasher?
To smash atoms together really fast. The resulting fragments are then analysed through sensors to determine what happened.
What is the main metal of stainless steel?
Primarily iron, with some carbon and nickel in the alloy. The precise proportions will determine the properties of the resulting steel.
