Brown hair is dominant over red hair. What will the genotypes and phenotypes of the offspring of a cross between a homozygous br
Artemon [7]

Answer:

1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.

2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.

3) The punnet square for cross between these parents can be shown as follows:

        B           b

B     BB       Bb

B     BB       Bb

4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.

5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).

Characteristics
Oduvanchick [21]

Answer:

One reason that Organism A and Organism C will be placed in different groups will be due  to their MODE OF NUTRITION.

As described in the question, Organism A has an autotrophic mode of nutrition which means that it has the capability to produce its own food. Organism C is a heterotroph which means it cannot produce its own food and hence will have different properties as compared to the organism A.

Vitamin water contains about as many calories as a soft drink. <br> a. True <br> b. False
lana66690 [7]
The answer is True

The calorie that you get from drinking vitamin water mostly comes from sugar/carbohydrate. The sugar content of vitamin water is high enough to become close with a soft drink. The calorie content would be around 6 calories per ounce.
