<span>The answer is conduction deafness. Conduction deafness occurs when sound waves have difficulty reaching different parts of the ear. Hearing aids can amplify the sound waves or use the bone to conduct sound instead of air. The other choices are caused by damaged structures or differences in the brain. Ordinary hearing aids are ineffective in those cases.</span>

A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times i

These genes could have arisen by gene duplication.

<h3>What is gene duplication?</h3>

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

  • Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
  • Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
  • Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.
lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc

Why do cells divide instead of just grow larger
hjlf
There are two main reasons why cells divide rather than continuing to grow larger and larger. One of the main reason is that the larger cell become more demanding, therefore the large cell will increase load on the machinery of the cell such as DNA. The other reason is that if the cell grow too large it will be difficult for the cell to move for nutrients and discard the waste across the cell membrane. Also the surface area for each cell will also be reduced, which is required for active functionality of a cell.
