When a BB male and a Bb female are crossed, 50% BB and 50% Bb genotypes are produced and a 100% black phenotype.
The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.
The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself. In this instance, the white fur is subordinate to the black fur. White fur is represented as b, while black fur is represented as B.
We can see that when we cross the BB male and Bb female, we will get a genotype that is 50% BB and 50% Bb, as well as a phenotype that is 100% black fur.
Parents: BB x Bb
Gametes: B, B, and B, b
Offspring: BB, BB, Bb, Bb
The genotypic ratio = 1:1
The phenotypic ratio = 1:0
Genotype probabilities:
P(BB) = 2/4 = 0.5 or 50%
P(Bb) = 2/4 = 0.5 or 50%

Before the orthopaedic surgeon could internally fixate the fractured femur, she performed manual
traction of the femur.
<span>One of the main initial treatments for the fractured femur injury is the application of traction splint. It includes applying distracting force between the lower leg and the relatively “fixed” base of the pelvis, which pulls the femur back into a more anatomical position.</span>
Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625
