The gene responsible for producing amyloid precursor protein (app) appears to explain the development of Alzheimer disease.

<h3 />

A form of dementia that progresses is Alzheimer's disease. A condition that adversely impacts memory, thinking, and behavior is referred to as dementia. The modifications make daily life more difficult. There are numerous possible causes of dementia, including diseases and brain traumas. Sometimes there is no known cause. The condition is typically diagnosed in patients over the age of 65.

Alzheimer's disease is typically described as having an "early onset" or "younger onset" if it is discovered earlier. Alzheimer's has no known cure, but there are medications that can halt the disease's growth. Alzheimer's disease is a brain ailment that gradually impairs thinking and memory abilities as well as the capacity to do even the most basic tasks. Additionally, psychological and behavioral changes are common in people with Alzheimer's.

If a heterozygous parent (AB/ab) is testcrossed to a homozygous recessive (ab/ab), what will the progeny phenotypic ratio be if

ra1l [238]

Answer:

Phenotypic ratio 1:1:1:1

Explanation:

A test cross is a cross between an individual with heterozygous genotype and a homozygous recessive individual, in order to ascertain the actual genotype of the dominant parent i.e whether homozygous or heterozygous.

In this case, which is a dihybrid cross involving two genes A and B. The allele A is dominant over allele a, since it masks the expression in a heterozygous state. The same applies for allele B and b.

Therefore, allele A and B are dominant alleles while allele a and b are recessive alleles.

In a cross between an heterozygous parent (AaBb) and a homozygous recessive (aabb), each individual will undergo meiosis and produce gametes. According to Mendel's law of independent assortment, the alleles of each individual get sorted into gametes independent of one another.

The four possible gametes produced by each parent are:

AaBb: AB, Ab, aB, ab

aabb: ab, ab, ab, ab

Thus, using a punnet square (see attached image), the possible 16 progenies will possess four different genotypes: AaBb (4), Aabb (4), aaBb(4), aabb(4)

Considering the four distinct genotypes, the phenotypes will also differ. Hence, the phenotypic ratio: 4:4:4:4 ~ 1:1:1:1
