After consulting a genetic map of Drosophila melanogaster, you find that two genes you are interested in lie 72 map units apart.

If you do a 2-point testcross for these two genes, what percentage of the progeny do you expect to be recombinant?

Answer:

The percentage of recombination frequency will be greater than or equal to 50%.

Explanation:

A distance of 72 map units is a substantial distance so two genes located this much distance apart will segregate almost independently or we can say that they will be considered as unlinked genes that is why the recombination frequency will be greater than or equal to 50%. Recombination frequency in turn gives us an idea of how many progeny are produced with genes which underwent crossing over during meiosis in parental gametes so that they have new combinations of genes which are different than parents leading to variations. In short in this example, 50% or more progeny will be recombinants.

How can the cells in a multicellular organism differ from each other when they all have identical DNA
aleksley [76]
Well all cells in a multicellular organism have the same exact DNA (except for sex cells). But what makes each type of cell different physically and functionally is the genes that are expressed in those cells.So for like example a different section of the DNA molecule is expressed in a nerve cell than a skin cell.

What were Punnett squares developed to do?
WITCHER [35]

Answer: to predict the probability of offspring genotypes

Explanation: Punnett squares are developed to predict the probability of offspring genotype. Punnett square is a square shaped diagram used for predicting the possible genotypes of a cross between two organisms. Punnett square is named after Reginald C. Punnett, who invented the approach. In punnett squares, the genotypes of the parents are written on the top and left hand side of the square while the possible genotypes of their offsprings are written in the boxes.
