Answer:
Chromosomes are a microscopic thread-like structure, and it is the part of a cell that carries hereditary information in the form of genes.
Homologous chromosomes the relationship between two chromosome, consists of the same gene sequence, each derived from one parent. They consist of alleles of the same type of genes in the same loci. Homologous chromosomes pair up during the process of meiosis 1. The part of the Homologous chromosomes can be exchanged during the process of recombination. Examples of these are 22 autosomal chromosomes in humans.
Non-homologous chromosomes do not belong to the same pair, they consist of alleles of different types. Non-homologous chromosomes do not pair up during the process of meiosis 1. The part of the Non-homologous chromosomes can be exchanged during the process of translocation. Examples are X and Y chromosomes.
The epiglottis
The cartilage in the throat that guards the entrance to the trachea and prevents fluid and food from entering it when a person swallows is known as the epiglottis
.
The epiglottis is an elastic flap located at the upper end of the larynx in the throat. The epiglottis is the valve that turns passage to either the esophagus or the trachea. The epiglottis allows air to enter the airway to the lungs during breathing, and during swallowing, it allows food and fluids to pass into the gastrointestinal tract.
This can be analyzed through molecular and DNA analysis.When fossils are examined, it should be thorough. Thus, certain anatomical indicators and DNA sequences are observed to describe the overall organism before it died. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
