Dizziness is usually caused by an upset in the balance centers of the inner ear, which is called vestibular system. This is where balance is regulated. Upsetting the vestibular balance results in brief and intense sensation of spinning. Dizziness is often initiated by rapid change in head movements. An individual may also experience dizziness because of pregnancy, headache, low or high blood pressure, etc.

In cats the allele for short hair is dominant over the allele for long hair. A short haired male and long haired female have kit

SCORPION-xisa [38]

Answer:

Genotype of parents: Ss x ss

Genotype of offsprings: Ss ss

Expected ratio of short to long: 2 : 2 = 1 : 1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents: Ss x ss

Genotype of offsprings: Ss ss

Expected ratio of short to long: 2 : 2 = 1 : 1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I

Bogdan [553]

Answer:

Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like 'photocopies' of original parent chromosomes; joined together at the Centromere.

They are exactly similar in all ramification; with the same gene and allele compositions..

However; slight differences arise between the two identical sisters due to mutation from errors at replication;and also in the length of telomere repeats.

Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

However, they are genetically similar in composition; if they are contained in homologous chromosomes. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .
