damaskus [11]

The term faecal incontinence refers to lack of control over bowel movements that is not caused by an organic problem.

The inability to control bowel motions results in faeces (stool) leaking unexpectedly from the rectum in faecal incontinence. Fecal incontinence, also known as bowel incontinence, can range from the infrequent leakage of faeces when passing gas to a total lack of bowel control.

Faecal incontinence is frequently brought on by muscle or nerve injury, constipation, and diarrhoea. Damage to the muscles or nerves may be brought on by ageing or giving birth. Faecal incontinence can also develop in those who are unaware that they need to pass stool. We refer to this as passive incontinence.

Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
