According to the FDA, products labeled gluten-free must contain less than 20 milligrams of gluten. Have a nice day!

According to the FDA, food products labeled "gluten-free" or "no gluten" must contain at least 20 parts per million in order to be in an acceptable range. Especially since people with celiac disease, when the small intestine is sensitive to gluten, can only tolerate a tiny amount.

Two parents who are heterozygous for type A blood and have sickle cell trait have children.

GuDViN [60]

This question is incomplete, but here is the complete question below.

In humans , blood type is a result of multiple alleles: $I^{A}$ , $I^{B}$ , $i^{o}$ .

A few simple rules of blood type genetics are that:

$I^{A}$ is dominant over $i^{o}$

$I^{B}$ is dominant over $i^{o}$ , and

$I^{A}I^{B}$ are codominant

Two plants who are heterozygous for type A blood and have sickle cell trait have children. Answer the following questions:

a. What is the genotype of the parents?

b. What are the genetic make ups of all the possible gametes they can produce.

c. Complete the dihybrid Punnet square to determine the frequency of the different phenotypes in the offspring.

(NOTE: Consider blood type and normal versus mutant hemoglobin in the various phenotypes.)

Answer:

a) $I^{A}i^{o}AS$

b) $I^{A}A,I^{A}S,i^{o}A,i^{o}S$

c) The dihybrid table is shown in the explanation below and the frequency of the different phenotypes of the offspring are in the ratio of 3:6:3:1:2:1

Explanation:

From the question the genotype of the parents can be determined:

Given that Two parents are heterozygous for type A and have sickle cell trait.

∴ heterozygous for type A will be = $I^{A}i^{o}$ &

heterozygous for having sickle cell traits = AS

Therefore, the traits can be determined the genotype of the parents can be determined as: $I^{A}i^{o}AS$

the genetic make ups of all the possible gametes they can produce can be determined if the parent are self crossed.

If $I^{A}i^{o}AS$ self crossed, we have:

$I^{A}$ $i^{o}$

A $I^{A}A$ $i^{o}A$

S $I^{A}S$ $i^{o}S$

∴ The genetic makeups of all the possible gametes they can produce are:

$I^{A}A$ , $I^{A}S$ , $i^{o}A$ , $i^{o}S$

Below shows the dihybrid Punnet square and the frequency of the different phenotypes in the offspring

I^{A}A I^{A}S i^{o}A i^{o}S

I^{A}A I^{A}I^{A}AA I^{A}I^{A}AS I^{A}i^{o}AA I^{A}i^{o}AS

I^{A}S I^{A}I^{A}AS I^{A}I^{A}SS I^{A}i^{o}AS I^{A}i^{o}SS

i^{o}A I^{A}i^{o}AA I^{A}i^{o}AS i^{o}i^{o}AA i^{o}i^{o}AS

i^{o}S I^{A}i^{o}AS I^{A}i^{o}SS i^{o}i^{o}AS i^{o}i^{o}SS

$\frac{3}{16}$ = 18.75% : Blood type A, normal hemoglobin (normal RBCs) = I^{A}I^{A}AA, I^{A}i^{o}AA, I^{A}i^{o}AA

$\frac{6}{16}$ = 37.5% : Blood type A, normal and mutant hemoglobin (sickle cell trait) = I^{A}I^{A}AS, I^{A}i^{o}AS, I^{A}I^{A}AS, I^{A}i^{o}AS, I^{A}i^{o}AS, I^{A}i^{o}AS

$\frac{3}{16}$ = 18.75% : Blood type A, mutant hemoglobin (sickle cell anemia) = I^{A}I^{A}SS, I^{A}i^{o}SS, I^{A}i^{o}SS

$\frac{1}{16}$ = 6.25% : Blood type O, normal hemoglobin (normal RBCs) = i^{o}i^{o}AA

$\frac{2}{16}$ = 12.5% : Blood type O, Blood type A, normal and mutant hemoglobin (sickle cell trait) = i^{o}i^{o}AA, i^{o}i^{o}AS

$\frac{1}{16}$ = 6.25% : Blood type O, mutant hemoglobin (sickle cell anemia) = i^{o}i^{o}SS

I hope that helps alot!

The ability of a muscle to contract and relax is dependent on the flow of what substance out of and into its storage site in the

tiny-mole [99]

Answer:

Calcium.

Explanation:

Muscle cells are the important for the body as they are involved in the bodily movement. Three different type of muscle are smooth muscle, cardiac muscle and skeletal muscle.

The sarcoplasmic reticulum contains the stored calcium in the muscle cell. The calcium is important ion that plays an important role in the muscle contraction. The actin and myosin protein functioning also depends on the the calcium ion.

Thus, the correct answer is option (B).
