Given: The mutation rate per nucleotide is 4 x 10^{-8}. There are 1500 nucleotides per locus.

To find: The mutation rate per locus for the locus of length 1500 nucleotides.

Method: Simple multiplication of the mutation rate per nucleotide with number of nucleotides per locus will give the answer

Solution:

The mutation rate per nucleotide = 4 \times 10^{-8}

The number of nucleotides per locus = 1500

The mutation rate per locus = mutation rate per nucleotide x number of nucleotide per locus = 4 \times 10^{-8} \times 1500 = 6 \times 10^{-5}.

Answer:

III3 will be "pp" lower case p

II2 will be Pp

Explanation:

As we know the trait is caused by dominant alleles. III3 is not affected so she will have two recessice alleles so 2 lower case p.

III2 is affected so the person will have one dominant allele P and one recessive. The dominant is from the father and the recessive is from the mother.

Hope that helps

The answer is bioaccumulation. Bioaccumulation is when toxins build up in a food chain. The animals at the top of the food chain are affected most severely because the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.

In some species of Drosophila, there are genes on the Y chromosome that are not on the X chromosome. Imagine that a new allele a
mr_godi [17]

Answer:

True

Explanation:

The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.

However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.

Thus, true is the correct answer.

the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
