Answer: the blue squares are B and the white squares are BB
Explanation:
In the given question,
suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.
The genotype for white, disc shape fruits is- AABB
the genotype for yellow, long fruits is- aabb
F1 progeny will be- AABB x aabb
AaBb
F2 cross- AaBb x AaBb
AB Ab aB ab
AB <em>AABB AABb AaBB AaBb</em>
Ab <em>AABb AAbb AaBb Aabb</em>
aB <em> AaBB AaBb aaBB aaBb</em>
ab <em>AaBb Aabb aaBb aabb</em>
The genotype of F2 cross are-
1. 9/16 A- B- disc-shaped (like F1)
2. 3/16 A- bb spherical
3. 3/16 aa B- spherical
4. 1/16 aa bb long.
The percentage that is homozygous recessive is .3^2=.09
Answer:
See the answer below
Explanation:
The independent variable would be the type of animal (horse or dog).
I<u>n the course of an experiment, the independent variable is the variable whose value does not dependent on the value of any other variable in the experiment.</u> It is the variable that the researcher can control during the course of an experiment and whose manipulation changes or influences the actual variable the researcher is set out to measure.
<em>I this case, if an experiment is set up to test the hypothesis that horses can swim faster than dogs, the actual variable that the experimenter would set out to measure would be the speed at which the two animals can swim. As the animals are interchanged for each other, the speed of swimming would vary. </em>
Hence, the type of animal is the independent variable while the speed at which swimming takes place would be the dependent variable.
