Answer:

B) 1/2 X 1/2 = 1/4

Explanation:

It happens when both the parents are heterozygous for the trait. The cross related to this result is shown as under:

                          Father           Mother

                             Bb       x        Bb

                             /   \                 /   \

Gametes:           B      b            B      b

                          |        |              |       |

Probability:      1/2     1/2          1/2    1/2

The probability of formation of 'b' gamete from father is 1/2 because there are only two gametes 'B' and 'b' and out of these two one will be assorted as 'B' and another one as 'b' and from mother also the probability of formation of 'b' gamete is 1/2.

Now the assortment of gametes with each other is an independent event i.e. any gamete from father can fuse with any gamete of mother so the overall probability of formation of 'bb' genotype will be 1/2 x 1/2 = 1/4.

Sloan [31]

Females who lift weights are not going to develop large, bulky muscles because they have lower testosterone levels than men.

Testosterone is defined as the main sex hormone of the males that are produced in the testicles.

The functions of Testosterone include

  • bone mass,

  • fat distribution,

  • muscle mass and strength, and

  • the production of red blood cells and sperm.

This hormone is produced in small quantities in females therefore, females who lift weights are not going to develop large, bulky muscles.

The equation y = 8x + 12, where x is the number of hours and y is the total cost, represents what the surf instructor charges fo
irinina [24]
Simple problem my friend!

First we must replace X with -2,-1,0,1,2
then we plug in -2 in X. 8*-2 is -16 and adding 12 gives us a co ordinate of (-2,-4) now this is not enough so now we must do -1. 8*-1 is -8, + 12 gives us 4. so now our second co ordinate is (-1,4). i will do 1 more co ordinate and then you should be able to finish the problem by yourself :) we now plug in 0 to replace X. 8*0 is 0, easy and 0+12 is 12. so the third co ordinate is (0,12) when you have put all the dots on the graph be sure to draw a line through them and by the way, this is not a biology question lol, good luck!
