What does a 3 1 phenotype mean?.

1 answer:

3 0

3:1 phenotype ratio means that three offspring will have a dominant phonotype. Then there is one offspring that will have a recessive genotype, and thus the recessive phenotype.

A 3:1 ratio is the relative fraction of phenotypes among progeny (offspring) results following mating between two heterozygotes, where each parent possesses one dominant allele and one recessive allele at the genetic locus in question.

A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another.

A monohybrid cross results in a phenotypic ratio of 3:1.

On each turn of the knob, a gumball machine is equally likely to dispense a red, yellow, green or blue gumball, independent from

Answer:

$P(R_2Y_2C_2B_2) = 0.03845$

Step-by-step explanation:

Given

$Balls = 4$ --- [R, Y, C and B]

$Turns = 8$

Required

$P(R_2Y_2C_2B_2)$

Since each of the 4 balls are equally likely, their probability is:

$P(R) = P(Y) = P(C) = P(B) = \frac{1}{4}$

From $P(R_2Y_2C_2B_2)$ , we have:

$R = Y = C = B = 2$

$Total = 8$

So, the total arrangement of the 8 balls is:

$Arrangement = \frac{8!}{2!2!2!2!}$

$Arrangement = \frac{40320}{2*2*2*2}$

$Arrangement = \frac{40320}{16}$

$Arrangement = 2520$

The individual probability of each ball, when put together is

$Probability = P(R)^2 * P(Y)^2 * P(C)^2 * P(B)^2$

$Probability = (1/4)^2 *(1/4)^2 *(1/4)^2 *(1/4)^2$

$Probability = (1/16) *(1/16) *(1/16) *(1/16)$

$Probability = \frac{1}{65536}$

Lastly:

$P(R_2Y_2C_2B_2) = Arrangement * Probability$

$P(R_2Y_2C_2B_2) = 2520 * \frac{1}{65536}$

$P(R_2Y_2C_2B_2) = \frac{2520 }{65536}$

$P(R_2Y_2C_2B_2) = 0.03845$

Please help me !!!! and explain !

Find the scale factor of the two cylinders:

Figure A has an r of 4 and figure B has an r of 2:

2 / 4 = 0.50, so Figure B is half the size of Figure A.

Since you want the volume, which is measured in cubic units, you need to cube the scale factor:

0.5^3 = 0.125

Multiply the volume of Figure A by the scale factor:

352 x 0.125 = 44 cubic feet.

Given two sides with lengths 34 and 14, which of these lengths would NOT work for the third side of a triangle? 18, 34, 44, 22,

Bas_tet [7]

Two sides are 34 and 14.

The third side can't be longer than (34 + 14) = 48, because the 34 and the 14
together could not reach from one end of it to the other.

The third side also can't be shorter than 20, because the 20 and the 14 together
could not reach from one end of the 34 to the other.

So 18 doesn't work. (18 + 14) = 32 ... they couldn't cover the 34 .

Write the prime factorization of 48. use exponents when appropriate and order the factors from least to greatest

horrorfan [7]

What can be divided? For example, for 48 you can divide 1, and 48 and you can also divide it by two which equals to 24 so keep writing that from least to greatest. You don't have repeat answers.
