<span>Hypotheses are typically written in an "if-then" format. This statement concerning algal increases could be properly written as "if the red algal concentration is higher than usual, then there will be dead fish floating on the surface of the water." These statements allow us to test the belief and see if there are causal links between the two.</span>
Answer:
The correct answer is -
Parental - BB and bb
F1
Genotypes: 100% Bb
F2
Genotypes: ¼ BB, ½ Bb, ¼ bb
Explanation:
It is given that a cross between a brown and a silver-blue mink produces all brown offspring and it is only possible if brown is dominant over silver blue in true breed cross, assume brown trait is represented by B and silver-blue is b then parents will be
BB and bb
B B
b Bb Bb
b Bb Bb
Cross between F1 individuals: Bb cross Bb
gametes : B, b and B, b
B b
B BB Bb
b Bb bb
the genotype of F2 : 1:2:1 = ¼ BB, ½ Bb, ¼ bb
