In Drosophila, the bar mutant is characterized by eyes that are restricted to a narrow, vertical bar. When a bar female is mated

Lelechka [254]

Answer:

See the answer below

Explanation:

a) The mode of inheritance of the bar mutant is X-linked and dominant.

Assuming that barness is represented by the allele B.

Bar female = $X^BX^B$ or $X^BX^b$

Wild type male = $X^bY$

Bar female x wild type male:

$X^BX^B$ x $X^bY$

$X^BX^b$ $X^BY$ $X^BX^b$ $X^BY$

All of the F1 flies are bar because a single B allele is required for the trait to be expressed.

Bar male x wildtype female

$X^BY$ x $X^bX^b$

$X^BX^b$ $X^BX^b$ $X^bY$ $X^bY$

All the female offspring are barred while all the males are wildtype barred resulting in a 50/50 (857/905 is approximately 50/50) ratio of barred/wildtype offspring.

b) Genotypes of each of the cross above, including the parents and the F1 generations.

1. $X^BX^B$ x $X^bY$

$X^BX^b$ $X^BY$ $X^BX^b$ $X^BY$

2. $X^BY$ x $X^bX^b$

$X^BX^b$ $X^BX^b$ $X^bY$ $X^bY$

What are known causes of epigenetic effects, and how do they

OverLord2011 [107]

Answer:

Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.

As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.

Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.

Explanation:

Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.
