uently, offspring from the previous year's litter help rear their parents' new pups by regurgitating food for the lactating mother and for her young. It turns out that the number of surviving pups increases an average of 1.5 for every helper, compared to only 0.5 pups surviving when raised by the parents alone. A. The recruitment of previous offspring to help raise new pups is called: B. Why would young jackals forego their own breeding to help their mother raise new
Molecular Techniques
Molecular techniques are methods employed in molecular biology, genetics, biochemistry, and biophysics to manipulate and analyze nucleic acids (deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)), protein, and lipids. Techniques in molecular biology are employed to investigate the molecular basis for biological activity. These techniques are used to analyze cellular properties, structures, and chemical reactions, with a focus on how certain molecules regulate cellular reactions and growth.
DNA Fingerprinting and Gel Electrophoresis
The genetic makeup of living organisms is shown by a technique known as DNA fingerprinting. The difference is the satellite region of DNA is shown by this process. Alex Jeffreys has invented the process of DNA fingerprinting in 1985. Any biological samples such as blood, hair, saliva, semen can be used for DNA fingerprinting. DNA fingerprinting is also known as DNA profiling or molecular fingerprinting.
Molecular Markers
A known DNA sequence or gene sequence is present on a chromosome, and it is associated with a specific trait or character. It is mainly used as a genetic marker of the molecular marker. The first genetic map was done in a fruit fly, using genes as the first marker. In two categories, molecular markers are classified, classical marker and a DNA marker. A molecular marker is also known as a genetic marker.
DNA Sequencing
The most important feature of DNA (deoxyribonucleic acid) molecules are nucleotide sequences and the identification of genes and their activities. This the reason why scientists have been working to determine the sequences of pieces of DNA covered under the genomic field. The primary objective of the Human Genome Project was to determine the nucleotide sequence of the entire human nuclear genome. DNA sequencing selectively eliminates the introns leading to only exome sequencing that allows proteins coding.
Question.2. The black-backed jackal lives in the brushland of Africa, where monogamous pairs defend territories, hunt cooperatively, and share food. Frequently, offspring from the previous year's litter help rear their parents' new pups by regurgitating food for the lactating mother and for her young. It turns out that the number of surviving pups increases an average of 1.5 for every helper, compared to only 0.5 pups surviving when raised by the parents alone.
A. The recruitment of previous offspring to help raise new pups is called:
B. Why would young jackals forego their own breeding to help their mother raise new pups? Explain your answer in the context of Hamilton's Rule.
C. Young jackals that help their parents raise new pups usually have increased reproductive success and/or direct fitness later in life. Provide two potential explanations for this effect.
