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.

In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farme

irina1246 [14]

Answer:

a. Genotype in F1 - TtBb

Phenotype in F1 - tough pods, bush-type growth

b. Proportion of F2 that are heterozygous for bush-type growth form = 5/8

c. Proportion of the F2 with tender pods = 1/4

d. Proportion of F2 that are heterozygous for growth form and have tender pods = 1/8

Explanation:

Since the two traits are located on different chromosomes, they will independently assort during gametes formation. T is dominant over t and B is dominant over b.

Two true-breeding varieties were crossed at the beginning of the program:

TTBB x ttbb

All F1 plants will have the genotype TtBb with tough pods and bush-type growth form.

Advancing the cross to F2:

TtBb x TtBb

Progeny

1 TTBB - tough pods, bush-type

2 TTBb - tough pods, bush-type

2 TtBB - tough pods, bush-type

4 TtBb - tough pods, bush-type

1 TTbb - tough pods, climbing-type

2 Ttbb - tough pods, climbing-type

1 ttBB - tender pods, bush-type

2 ttBb - tender pods, bush-type

1 ttbb - tender pods, climbing-type

Proportion of F2 that are heterozygous for bush-type growth form = 10/16 = 5/8

Proportion of the F2 with tender pods = 4/16 = 1/4

Proportion of F2 that are heterozygous for growth form and have tender pods = 2/16 = 1/8

Why don't hybrids reproduce

nordsb [41]

An animal category is a gathering of creatures that can breed together that can deliver fruitful prosperity.

Ligers, Mules, They aren't species, they are a mix of 2 animal groups subsequently the name is half and half, they can't recreate in light of the fact that, the two distinct species have two unique quantities of chromosomes. Species can duplicate inside of their own species, since every person inside of the species has the same number of chromosomes.

The crossover's can't imitate in light of the fact that sex cells would never be prepared as their chromosomes would not be right. The half breeds would never happen in nature, they were made by man, I don't know how they fulfilled this, yet, at any rate, thats why the mixtures can't replicate.

Give an example of how you could determine whether or not a trait was displaying incomplete dominance. What would you do? What w

Vinvika [58]

An example of incomplete dominance is: A snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower when neither the white or the red alleles are dominant.
