Answer:

The correct answer is option B, All four children have genes for blue eyes.

Explanation:

The allele (representative of any trait) carried by genes expresses themselves at specific locus devise a phenotype. Traits exhibited can be represented by genotype and phenotype of an individual.  

Here in this example, blue colour of eyes is a trait which is common in all the children of the family, this simply signifies that genes carrying the alleles is same in all the children.

the salivary glands, stomach, and pancreas secrete ____________ enzymes to break down triglycerides into monoglycerides, fatty a
likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

La polidactilia en la especie humana se debe a un alelo dominante. Entre Francisco y Martha, ambos abuelos de Santiago, uno de e
lesya [120]

Answer:

  • Abuelo/a con polidactilia heterocigoto, Pp
  • Abuelo/a normal, pp
  • Juan normal, pp
  • Esposa de Juan con polidactilia, PP o Pp
  • Santiago con polidactilia, Pp

Explanation:

<u>Datos disponibles</u>:

  • Polidactilia es causada por un alelo dominante, P.
  • El alelo recesivo p produce numero normal de dedos.
  • Francisco y Martha → Abuelos → uno de ellos con polidactilia
  • Juan → Hijo → Normal, pp
  • Santiago → Nieto → Polidactílico

Uno de los padres, ya sea Francisco o Martha, es polidactílico, lo que implica que ésta persona tiene, por lo menos, un allelo dominante en su genotipo, P- (El simbolo "-" esta representando un alelo dominante o uno recesivo).

Si Juan es normal, entonces su genotipo es pp, lo que significa que recibió un alelo recesivo de su padre y otro de su madre. Es decir que el parental policactílico es heterocigota, de forma que pudo heredarle un alelo recesivo a Juan. El otro parental probablemente sea normal, pp, pudiendo solo heredarle a Juan el alelo recesivo.

Entonces, uno de los padres tiene genotipo Pp (heterocigota) y el otro pp (homocigota recesivo).

Juan es norma, pp.

Santiago, hijo de Juan, es polidactílico, lo que implica que lleva en su genotipo por lo menos un alelo dominante, P. Pero Juan solo pudo heredarle un alelo recesivo, p. Por lo tanto, Santiago es heterocigota para la característica, Pp, y heredó el alelo dominante de su madre, que puede ser homcigota dominante PP o heterocigota Pp.

Supongamos que Francisco es polidactílico y Martha normal.

<u>1º Cruza</u>: Francisco x Martha

Parentales) Pp    x    pp

Gametas) P    p     p      p

F1) 1/2 = 50% Pp

    1/2 = 50% pp → Juan

<u>2º Cruza</u>: Juan  x Esposa (opción uno: esposa homocigota dominante)

Parentales) pp    x     PP

Gametas)   p    p      P     P

F2) 4/4 = 100% Pp → Santiago

<u>2º Cruza</u>: Juan  x  Esposa (opción dos: esposa heterocigota)

Parentales)  pp    x     Pp

Gametas)   p    p      P     p

F2) 1/2 = 50% Pp → Santiago

      1/2 = 50% pp
