In pea plant the trait of yellow seeds (YY) is dominant over green seed (yy). Explain the inheritance pattern of F1 ad F2 genera

storchak [24]

Answer:

F1= All Yy

F1= All yellow

F2= 1/4 YY: 1/2 Yy: 1/4 yy

F2= 3/4 yellow: 1/4 green

Explanation:

The allele for the yellow-colored seeds (Y) is dominant over the allele that imparts green phenotype (y). A cross between two pure breeding yellow seeded and green seeded plants would obtain all yellow seeded plants in the F1 generation. Self-pollination of F1 progeny would obtain F2 generation in following phenotype and genotype ratio:

Phenotype ratio= 3/4 yellow: 1/4 green

Genotype ratio= 1/4 YY: 1/2 Yy: 1/4 yy

What are two theories proposed to explain Primate Origins and how do they relate to traits we see in modern primates

GREYUIT [131]

Answer:

The level of specialization is given by the function.

The function of the organ makes the cell as it becomes mature, its more specific function becomes.

First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.

After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.

Explanation:

The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.
