In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

A student added a solution to the plant cell shown in image 1 which resulted in the plant cell undergoing changes, as shown in i

Ymorist [56]

Answer:

Plasmolysis

Explanation:

In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.

The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.

The image 2 plant cell is exposed to a solution which is high concentrated solution.

Due to this high concentrated solution the water present in the cell is send out by exosmosis.

Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.

This shrinkage of protoplasm by loss of water is called plasmolysis.
