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

This compressed, slender body shape is beneficial because it allows the fish to easily fit into vertical crevices. This is probably why the fish live on coral reefs and in rocky areas, because there are enough crevices for these fish to fit into.

When you work in a School Lunch program, you’re bound to face challenges that pop up seemingly out of nowhere. That’s just the nature of serving hundreds or even thousands of students each day.

But, when you keep encountering the same Child Nutrition program problems, over and over, day after day, it’s likely more than just a coincidence.

Instead, there probably are bigger issues causing these problems.

The bad news is that it often can be unclear what these bigger issues are, which makes fixing them almost impossible.

The good news? We at Harris School Nutrition Solutions have spent thirty years working with the men and women of Child Nutrition programs all across the U.S., helping to diagnose and solve their School Lunch problems.

So, we figured we’d share with you some of the common school lunch-line challenges we’ve seen over the years, the real issues behind those challenges, and of course the solutions to both.
