Answer:

A. Matrix A

Step-by-step explanation:

When you put a systems of linear equations in matrix form, you take only the coefficients of the xy terms and sort them. x goes first, y comes after, and the numbers after the bars are the constants.

Answer:

The number of expected double crossover progeny is 47.275

To the nearest whole number 47

Step-by-step explanation:

Consider the provided information.

The distance between withered wings (whd) and smooth abdomen (sm) is 30.5,

That means the probability of crossover between them is 0.305.

The distance between smooth abdomen (sm) and speck body (sp) is 15.5,

That means the probability of crossover between them is 0.155

The resulting phenotypically wild-type females were mated with males that had the mutant phenotype for all three traits,

That means the expected frequency of double crossover progeny will be:

0.305×0.155 = 0.047275

It is given that they producing 1000 offspring, therefore,

0.047275×1000 = 47.275

The number of expected double crossover progeny is 47.275

To the nearest whole number 47

The opposite process rule says to solve for ________. a known variable by replicating the process used to form the original equa

ioda

Answer:

An unknown variable by reversing the process used to form the original equation.

Step-by-step explanation:

The opposite process rule says to solve for - an unknown variable by reversing the process used to form the original equation.

If an equation indicates an operation such as addition, subtraction, multiplication, or division, solve for the unknown variable by using the opposite process.

For example:

Lets say we have to find $x+25=35$
