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

Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to

Natali [406]

Answer:

The correct answer is: do not enter into a plexus and directly connect to the structures they supply.

Explanation:

The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.

The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.

The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.
