Answer:

Yes

Explanation:

A primer is a short, single-stranded DNA sequence used in the polymerase chain reaction (PCR) technique. In the PCR method, a pair of primers is used to hybridize with the sample DNA and define the region of the DNA that will be amplified. Primers are also referred to as oligonucleotides.

What is the probability of sampling a homozygous recessive individual from a population of 100 tree frogs if the the recessive a
Usimov [2.4K]

Answer:

The probability of sampling a homozygous recessive individual from a population of 100 tree frogs indicates that, the frequency of latent allele is 0.06 for example q2 is 0.06. Thus, it has been implies that each 6 tree frogs have the passive allele out of 100. So, the likelihood of accepting the tree frogs with homozygous passive tree frogs will be essentially 6%.

Qué recomendarías para evitar que destruyamos nuestro Planeta
konstantin123 [22]

Las acciones humanas están alterando el delicado equilibrio ambiental. En consecuencia, yo recomendaría aplicar diferentes acciones a nivel individual para preservar nuestro planeta.

La contaminación de los ecosistemas terrestres y acuáticos está poniendo en grave peligro los ecosistemas del planeta, con lo cual es imperativo disminuir los niveles de contaminación.

Algunas de las acciones necesarias que pueden ser aplicadas a nivel individual con el fin de proteger nuestro planeta son la reducción de la contaminación mediante el ahorro de energía y la conservación de recursos naturales.

  • La compra de productos ecológicos, la reducción del uso de materiales no biodegradables (por ejemplo, plásticos), el uso de medios de transporte público o la bicicleta, representan medidas contendientes a diminuir los niveles de contaminación.

  • El reciclado de materiales puede también ayudar a ahorrar energía, con lo cual evitando la contaminación que resulta del proceso industrial de fabricación de manufacturas.

  • Disminuir el uso de agua también es una medida para proteger nuestro planeta, ya que los organismos productores en un ecosistema (por ejemplo, las plantas) necesitan del agua para capturar y almacenar del carbono durante la fotosíntesis.

HELP ME PLEASE!!!!!
Grace [21]

The correct answer is option B. Genotype AA, phenotype-Unaffected.

The cystic fibrosis is a condition caused by the inheritance of the two recessive allele, It is an autosomal recessive disease.

In the given case, the parents are carriers, and the carriers are always heterozygotes. Hence, the phenotype of the both parent should be Aa. A possible cross of the parents is shown in the figure below.

In case, the progeny have a single dominant trait, the child would not be affected, but will be a carrier and can pass the disease to offspring. In case, the child inherit both the dominant allele (homozygous dominant) from the parents, then he/she would be unaffected. In case, the phenotype of the child is homozygous recessive then it would be affected.
