Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.

In eukaryotic cells, all the genetic information, in other words, the DNA is found in the nucleus, where its arranged in chromosomes. Therefore, the answer is A).
In the other hand, in prokaryotic cells, it isn't inside any special structure. Instead, it's just dispersed through the cytoplasm.

<h3>
what is pair bonding?</h3>
Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.
The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.
The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.
Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.
