Meiosis allows for the reshuffling of maternally and paternally-inherited alleles between different genes, thus allowing for hig

h genetic diversity in gamete genotypes, and thus offspring produced. Which of the following correctly relates a mechanism of reshuffling alleles of different genes with respect to each other with the location of genes on chromosomes? recombination reshuffles alleles of two genes that lie on the different chromosome types, whereas independent assortment reshuffles alleles of two genes that lie on the same chromosome type. recombination reshuffles alleles of two genes that lie on the same chromosome type, whereas independent assortment reshuffles alleles of two genes that lie on different chromosome types.

Recombination reshuffles alleles of two genes that lie on the same chromosome type, whereas independent assortment reshuffles alleles of two genes that lie on different chromosome types.

Explanation:

Alleles are two forms of same gene, they are located on the same loci of the homologous pair.

Recombination occurs when alleles from two homologous chromosomes get reshuffled during crossing over in meiosis.

Independent assortment refers to the tendency of alleles to be inherited independently from one generation to other.

<span>Rhabdomyolysis constitutes a common cause of acute renal failure and presents paramount interest. A large variety of causes with different pathogenetic mechanisms can involve skeletal muscles resulting in rhabdomyolysis with or without acute renal failure. Crush syndrome, one of the most common causes of rhabdomyolysis presents increased clinical interest, particularly in areas often involved by earthquakes, such as Greece and Turkey. Drug abusers are another sensitive group of young patients prone to rhabdomyolysis, which attracts the clinical interest of a variety of medical specialties. We herein review the evidence extracted from updated literature concerning the data related to pathogenetic mechanisms and pathophysiology as well as the management of this interesting syndrome. Keywords: Rhabdomyolysis, acute renal failure, myoglobin, crush syndrome The first case of the crush syndrome, which constitutes one of the main causes of rhabdomyolysis, was reported in Sicily in 1908, after an earthquake1,2. In 1930, in the Baltic area, an epidemic of myoglobinuria was observed due to consumption of contaminated fish. Interest in rhabdomyolysis and crash syndrome was stimulated during the World War II particularly after the bombing in London, where the victims developed acute renal failure and myoglobinuria1. Rhabdomyolysis is a rupture (lysis) of skeletal muscles due to drugs, toxins, inherited disorders, infections, trauma and compression3. Lysis of muscle cells releases toxic intracellular components in the systemic circulation which leads to electrolyte disturbances, hypovolemia, metabolic acidocis, coagulation defects and acute renal failure due to myoglobin4. The skeletal muscle consists of cylindrical myofibrils, which contain variant structural and contraction proteins. Actin and myosin, arranged in thin and thick filaments respectively, form the repeated functional units of contraction, the sarcomeres5. The sarcoplasmic reticulum constitutes an important cellular calcium storage. It is structurally connected to the t-tubules, that are formed by invaginations of the muscle cell plasma membrane, the sarcelemma, around every fibril (Figure 1). After the sarcelemma depolarization, the stimulation arrives, through the t-tubules junctions, at the sarcoplasmic reticulum, inducing the calcium ions release and triggering muscle contraction6.</span>

What gametes are produced by the following organisms:_______.
vova2212 [387]

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
