Assume a gene has 2 alleles q and q according to mendelian principles a homozygous male dog will produce what kind of gametes

2 answers:

6 0

During meiosis, the somatic cells of the spermatogenic cells in the seminiferous tubule divide into 4 haploid cells called spermatozoa (gametes). The genotype of the dog for the allele is qq, and therefore, each of the gametes will have an allele q.

Dog is homozygous and has qq alleles, So each gamete will have q allele.

Further explanation

Mendelian principles

His three important principles are following

1. Law of dominance

In parents cross for pure contrasting traits one trait will be transfer in next generation and hybrid offspring in phenotype will be prominant in one trait.

2. Law of segregation

It is stated as pair of allele segregate during formation of gametes, and randomly unite when fertilization occurs. Two alleles are inherited by Organisms for each trait.

3. Law of independent assortment

Law of independent assortment expresses that the alleles of (at least two) unique qualities get arranged into gametes freely of each other. As it were, the allele a gamete gets for one quality does not impact the allele got for another quality.

Homozygous

It can be defined as a single trail having same alleles, mostly there are two alleles in an organism and they are either recessive or dominant .

Alleles

An allele is a type variant form of gene. Here and there, various alleles can bring about various recognizable phenotypic characteristics, for example, extraordinary pigmentation.

Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Rem

vazorg [7]

Answer:

The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.

Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.

Leto [7]

<h2>A) option is correct </h2>

Explanation:

RNA is a linear polymer of ribonucleotides
Sugar in RNA is ribose instead of deoxyribose which is present in DNA
The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix

The parasympathetic nervous system is characterized by ____ preganglionic neurons and ____ postganglionic neurons.

soldier1979 [14.2K]

The parasympathetic nervous system is characterized by the location preganglionic neurons and the short postganglionic axons near the organs they innervate. The preganglionic neurons would originate in the spinal cord or the brainstem while the postganglionic neurons would lie outside the CNS.

In the pedigree that is shown, which represents Irene's allele combination?

Greeley [361]

The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is $X^{H} X^{H}$ .
