Alleles A and a reside at a locus on the same chromosome as a locus with alleles B and b. Aa Bb is crossed with aa bb and the fo
abruzzese [7]

Answer:

The two genes are linked together

Explanation:

<em>The conclusion that can be drawn about the arrangement of the genes on the chromosome in the Aa Bb parent is that the two genes are linked together. That is, they do not assort independently.</em>

When two genes are linked together, the number of recombinant offspring would be more than the number of offspring with parental traits. The frequency of recombination would also not exceed 50%.

<em>Recombination frequency = number of recombinant offspring/total number of offspring x 100%</em>

Number of recombinant offspring = 45 + 45 = 90

Total number of offspring = 45 + 45 + 5 + 5 = 100

Recombination frequency = 90/100 x 100% = 10%

Hence, the two genes Aa and Bb are said to be linked together.

compares the genomes of different organisms

compares the limbs of different organisms

molecular biology:

compares fossilized structures to living organisms

compares cells of organisms

EXPLANATION:

Comparative anatomy is the study of similarities and differences in the anatomy of different species.

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.
