Blood groups are a classic example of ______________ inheritance in humans?

1 answer:

8 0

There are multiple types of inheritance mechanisms in humans. The well-known ones are include autosomal dominant, where only one copy of the gene is enought for the individual to express that characteristic. Another type is autosomal recessive, in which an individual must receive a copy of the gene from both parents in order for the gene to be expressed. The type concerning blood groups is codominance and it is when two different versions of a gene are expressed. Both of the alleles have a role in the appearance of the characteristic. Both the A blood group and B blood groups are dominant; however, if both alleles are present, the individual has an AB blood group.

The question is incomplete as it does not have the options-

A) Gamma-aminobutyric acid (GABA)

B) Acetylcholine

C) Dopamine

D) Serotonin

Answer:

The correct answer will be option- Dopamine

Explanation:

Parkinson's disease is one of the movement disorders which gets worse with time. The disease is caused due to the degeneration of the neurons in the brain which are responsible for the body movement.

Although many brain areas are affected the most common result is due to the loss of neurons in the substantia nigra in which the neurons produce a neurotransmitter called dopamine which is responsible for the body movements.

Thus, Dopamine is the correct answer.

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t

Gelneren [198K]

Answer:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

A (colored seed) is dominant over a (colorless)
Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A Aa WxWx individual was test crossed (crossed with a homozygous recessive aa wxwx individual).

The homozygous recessive can only produce a wx gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 A Wx and 1/2 a Wx

The possible offspring resulting from the combination of those gametes is:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).
