Answer:
1. BbRr
2. Black, rough fur
3. bbRR
Explanation:
1. The genotype of the parents can be seen at the top of the cross "BbRr". The genotype is what alleles the parents have. In this case, it is the alleles of two different genes - for color and texture of fur. The genotype gives rise to 4 possible allele combinations that an offspring can inherit (BR, Br, bR or br)
2. The dominant allele is usually displayed as a capital letter, and the recessive as lowercase. Without further information, we will assume this is the case. The parents are heterzygous for both traits, meaning they each carry a dominant and recessive allele for both traits. That means the dominant allele will be expressed in the phenotype. Therefore, the guinea pigs will have black, rough fur.
3. Empty box shown in the attachment. We simply read the column and row of alleles that are contributing to this offspring's genotype. We can see looking at the square that from one parent (top) the baby will inherit bR, and from the other parent (left) it will inherit bR as well. This means the baby's genotype will be bbRR
hope this helps

Answer:
The correct answer would be:
A G C T
Human: 31 19 19 31
Cow: 28 22 22 28
Salmon: 29 21 21 29
Wheat 27 23 23 27
Yeast 31 19 19 31
Explanation:
According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.
It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:
A G C T
Human: 31 19 19 31 (A= T and G=C)
Cow: 28 22 22 28 (A= T and G=C)
Salmon: 29 21 21 29 (A= T and G=C)
Wheat 27 23 23 27 (100 - A+T = G+C)
Yeast 31 19 19 31 (A= T and G=C)
