Explain how the inheritance pattern shown in figure 1 supports a role for chloroplast genes in the production of chlorphyll in the variegated plants.

Respuesta :

Answer:

Answer b) The result of the experiment identifies that the color of the egg donor branch (parent) prevailed and assigned the color of the offspring.

-The female parental branches that were pure green or pure white had children of pure green or pure white, respectively.

- The female parental branches that were variegated allow to obtain the three types of offspring.

It is evident that the chloroplast shows maternal inheritance.

The branch that is pure green will produce eggs with green chloroplasts that will give rise to a pure green offspring. Thus, a pure white branch will have offspring with ovules with an exclusive content of white chloroplasts and will give rise to a pure white offspring.

If a branch is variegated, it is combined, some with only functional chloroplasts, some with only non-functional chloroplasts, and some with a mixture of chloroplasts. All three types of cells can give rise to ovules, leading to green offspring, white offspring, and variegated offspring.

Inheritance pattern is defined as the basic models for studying the transmission of a disease, or analysis of genetic characters.

The inheritance pattern shows that colour of the egg donor branch is prevailed and assigned the color to the offspring.

The female parental branches that were pure green and white has the progeny of pure green and white, similar to the parent.

The female variegated parental branches of females allow obtaining the three types of offspirng.

The branch of the pure green will produce the eggs with green chloroplasts, which will give rise to green offspring. The pure white branch will have ovules with exclusive white chloroplasts and will produce white offspring.

In the variegated branch, the functional chloroplasts, some with non-functional chloroplasts, and some with a mixture of chloroplasts.

Thus, offspring can be pure or variegated.
