Consider the results of a testcross performed on an organism heterozygous for 2 genes. For each scenario of gene arrangement for

the two genes, write the percentage of nonrecombinant and recombinant progeny that will result from the testcross.
Gene arrangement of 2 genes % Nonrecombinant progeny % Recombinant progeny
Unlinked (independently assorting)
Completely linked genes (with no crossing over)
Linked genes (with some crossing over)

Answer:

Following are the answer to the given points:

Explanation:

  • Unlinked - Nonrecombinant progeny (50%), recombinant progeny (50%)
  • Fully related genetics - 100% non-recombining genetic progeny (parental)
  • Incomplete connection of genes > 50% non-recombinant progeny < 50% crossover offspring. Connected genes

Mendel had established some essential concepts concerning inherited mechanisms such as the patterns of transmission of genes to offspring depending on their chromosomal placements. This same notion of linkage was offered to describe the pattern of the legacy of alleles on its chromosomal position.

Two different chromosomes have specific isoforms – for example, A and B which have two different features. As just a result, 50 percent of gametes are parental throughout type AB, and the other 50 percent of a recombinant in zygotes are quasi (aB & Ab) and 50 percent of the progenies that outcome from this mixture of gametes, therefore, are nonrecombinant in 50% and the cloned in 50 percent of the genetic makeup AaBb.

With two fully linked genes, e.g they exist on the very same chromosome and no cross-over occurs, all gametes are similar to parent types (AB and ab), like they do not split themself nor are diverse and culturally produced (nonrecombinants).

mrs_skeptik [129]

Answer:

d. None of these  

Explanation:

Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>

An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.

These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.

It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.

How are vaccinated individuals protected against a virus?
aleksandrvk [35]
Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
AveGali [126]

Answer:

In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.
