Answer: B. Blood dripping from the murder weapon.
Explanation: In bloodstain pattern analysis, blood spatters behave in accordance with some scientific laws in relation to what caused the bloodshed, the position of the victim and the perpetrators, and the velocity at which the blood is spattered. Since the blood trail is leading away from the stabbed victim, the blood trail is most likely created by the dripping of blood from the murder weapon
(B) 25% GG, 50% Gg, and 25% gg
<u>Explanation:</u>
Given:
Green is dominant and is coded by G
Albino is recessive and is coded by g
Two corn plants that are heterozygous for color are crossed.
The heterozygous condition of the plant would be Gg.
The cross is shown in the table attached.
According to the punnett square drawn,
The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)
= 25% GG , 50% Gg , 25% gg
Phenotypic ratio = 3 : 1 ( green : albino)
= 75% green, 25% albino
