If the green allele is designated as G, and the aurea allele is designated as GA , assign genotypes to the phenotypes listed. Dr
Katyanochek1 [597]

Answer:

in the mutated snapdragon plants, the green leaves started becoming yellow. this conditioned plant is known as, aurea, which has less chlorophyll than green plants.

Crosses had done between various combinations of green and aurea plants and the result was-                                                                                                                                                                green x green = all green

aurea x aurea =  2/3  aurea, 1/3 green

green x aurea = 1/2 green, 1/2 aurea  

here, the green allele is G, and the aurea allele is GA,  

according to the question, in  the cross of plants,

the green plants produced all green but some of the crosses of aurea phenotype also gave the green phenotype.

so it can be concluded that the green phenotype (the wild type) came from the recessive allele. No instances of incomplete dominance or codominance were shown.

Thus, the following genotypes would have their phenotypes, as follows:

GG - green  

GAGA - aurea

GGA - aurea

List the three principal hormones that regulate glucose metabolism. Explain the effects these molecules have on carbohydrate met
drek231 [11]

Answer:

The three hormones are insulin, glucagon, and GIP and GLP-1.

Explanation:

After the ingestion of carbohydrates, insulin increases in the blood generating peaks in blood glucose, therefore the hormone that will increase is insulin to lower blood glucose, promoting the entry of this monosaccharide into the cells.

Different from the moments when the person enters into physical activity, and blood glucose is low, therefore glucagon is activated and seeks to remove the energy reserves from the interior of the cell.

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).
