Answer:

DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.

Explanation:

DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.

Feather color in budgies is determined by two different genes, Y for pigment on the outside of the feather, and B for pigment on
Anvisha [2.4K]

Answer:

The two blue budgies are most likely to be yyBb each

Explanation:

there are 3 different scenarios possible for crossing blue budgies:

1) yyBB crossed with yyBB

this is not possible because it does not allow for the genotype yybb (white budgies)

2) yyBB crossed with yyBb

again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement

3) yyBb crossed with yyBb

which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring

Hope that answers the question, have a great day!
