<u>Answer:</u>
<em>The genetic instructions are found in </em><u><em>the nitrogen bases </em></u><em>within the DNA, which is contained in </em><u><em>nucleotide</em></u><em> inside the nucleus of the cells. </em>
<u>Explanation:</u>
Inside nucleotide there are nitrogen bases along with phosphate group and sugar group. The four nitrogen bases are <em>adenine, thymine, guanine and cytosine (ATGC). </em>
These four bases pair up with each other inside the nucleotide. The order in which these bases are placed determines the genetic codes. This passes the instructions and characteristics from the parents to offspring.
It has to filter out the small amount of oxygen in the water, unlike terrestrial creatures.
B- black allele;
b- brown allele;
The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb
The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being brown homozygote- bb- 25%
answer: 25%+25%=50% are homozygotes
