How can karyotype analysis explain genetic disorders lab 15 2 answers?

1 answer:

4 0

A karyotype is a picture in which the chromosomes of a cell have been stained so that the banding patterns of the chromosomes appear. This way it is possible to view abnormalities in the chromosomes. Disorders such as aneuploidy can be diagnosed by karyotype. It can also help identify local abnormalities on chromosomes such as abnormalities in chromosome length, and location of the centromere.

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

Which of these is the most important cause of adult onset epilepsy?

aev [14]

Answer:

neurocysticercosis

Explanation:

Cysticercosis is the infection caused by the cystic form of the pig's tapeworm, Taenia solium, and neurocysticercosis is when the central nervous system (CNS) is affected. It is usually possible through direct ingestion of helminth eggs, but it can also occur in a usual infestation (teniasis). It is an endemic condition in several countries in South America, Africa and Asia, accounting for about 29% of the causes of secondary epilepsy in these locations. It can also cause headache, hydrocephalus, meningitis, and even central nervous system infarction.
