The type of progeny produced by crossing white-flowered parental variety and first-generation hybrid. Introduction. Gregor Mendel was an Austrianmonk, who worked on a pea plant to observe the pattern of inheritance of certain characters from the parent plant to the offspring. He termed the genes as factors that were passing on from one generation to another. Based on this, he proposed three laws, which came to be known as Mendel’s law of genetics.

Expert Solution & Answer

Explanation of Solution

The cross made between the true-breeding white flower (rr) and first-generation hybrid(Rr) will produce red and white flowers. When this plant is crossed with a dwarf parent the progeny produced is as follows:

Gametes

R

r

Rr

(red flower)

rr

(white flower)

r

Rr

(red flower)

rr

(white flower)

The progeny produced from the cross will consist of 50% of white flowers and 50% red flowers.

Nicotiana glutinosa (2 n = 24) and N. tabacum (2 n = 48) are two closely related plants that can be intercrossed, but the F1 hybrid plants that result are usually sterile. In 1925, Roy Clausen and Thomas Goodspeed crossed N. glutinosa and N. tabacum and obtained one fertile F1 plant . They were able to self-pollinate the flowers of this plant to produce an F2 generation. Surprisingly, the F2 plants were fully fertile and produced viable seeds. When Clausen and Goodspeed examined the chromosomes of the F2 plants, they observed 36 pairs of chromosomes in metaphase I and 36 individual chromosomes in metaphase II. Explain the origin of the F2 plants obtained by Clausen and Goodspeed and the numbers of chromosomes observed.

A type of tomato (Solanum lycopersicum) produces fruit in three possible colors: red, orange, and green. You cross a true-breeding red-fruited plant with a true-breeding green-fruited plant, and all the F1 offspring are red. You intercross the red F1s, and the resulting F2 generation consists of 61 red-, 13 orange-, and 6 green-fruited plants. a) Assign the phenotypes to a modified 9:3:3:1 ratio (do not just calculate the actual ratio of the phenotypes). Show your work.

In a variety of tomato plant ,the leaves maybe pure green,pure white,or variegated (mixture). a)when 2 variegated plants were crossed,87 offspring were produced,of these 20 were green,46 were variegated and 21 remain died soon after germination.Draw a genetic diagram to explain these results,why did 21 of them died
