ter having a black body and apterous wings. The following distribution of traits was observed in the offspring.

Gray body, long wings 42
Gray body, apterous wings 9
Black body, apterous wings 41
Black body, Iong wings 8
Which of the following is supported by the data?

A) The alleles for gray body and long wings are dominant.
B) The alleles for gray body and long wings are recessive.
C) Genes for the two traits are located on two different chromosomes, and independent assortment occurred

Answer:

D) Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci.

Explanation:

According to the data shown above, we can see that at the crossing of the two flies the genes for the two characteristics are located close to each other on the same chromosome, and the crossing occurred between the two genetic loci.

As you may already know, a chromosome is a molecule formed by the correlation between DNA and proteins that keep the DNA compacted and prevent it from spreading.

Genetic loci, on the other hand, are regions on chromosomes where a specific gene for a specific trait is located.

If you used a slingshot to launch a bowling ball and a baseball with the same force, which would go further? Explain your reason
Alex Ar [27]

Answer: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.

What are the three main ways that common ancestry may be shown through homologies
Harrizon [31]

Answer:

Homology is a study of similar characters found in two species because of common ancestry.

Explanation:

1.Morphological homology: Species placed under same taxonomic category exhibit similar anatomical structures.

2.Ontogenetic homology: Species belongs to same taxonomic category embryological similarities

3.Molecular homology: Species show molecular similarities such as DNA,RNA and protein

An example of homology is seen in the skeletal strycture of vertebrates. That is arm of a human,leg of a cat,fin of a whale and wing of a bat.
