Haemoglobin is found in red blood cells and carries oxygen from the lungs to the rest of the body, while myoglobin is found in muscles and stores oxygen for muscle use.

• Haemoglobin is found in red blood cells, while myoglobin is found in muscles.

• Haemoglobin carries oxygen from the lungs to the rest of the body, while myoglobin stores oxygen for muscle use.

• Haemoglobin has a higher affinity for oxygen compared to myoglobin.

• Haemoglobin consists of four protein subunits, while myo...read more

The most important hormone during child birth is oxytocin.

• Oxytocin is responsible for stimulating contractions of the uterus during labor.

• It also plays a role in bonding between mother and baby.

• Oxytocin is sometimes administered to induce or speed up labor.

• It is often referred to as the 'love hormone' due to its role in social bonding and maternal behavior.

Mitochondrial inheritance is the passing of genetic material through the mitochondria, which is inherited exclusively from the mother.

• Mitochondrial DNA is only inherited from the mother, as the father's sperm does not contribute mitochondria to the embryo.

• Mutations in mitochondrial DNA can lead to various genetic disorders, such as Leber's hereditary optic neuropathy and mitochondrial myopathy.

• Mitochondrial inheritance can be traced through maternal lineage, making it useful ...read more

Founder effect is the reduced genetic diversity that results when a population is descended from a small number of colonizing ancestors.

• Occurs when a small group of individuals establishes a new population

• Genetic diversity is limited to the alleles present in the founders

• Can lead to increased frequency of certain genetic disorders

• Common in isolated populations like island communities

Incomplete dominance is a genetic concept where neither allele is completely dominant over the other, resulting in a blending of traits.

• In incomplete dominance, the heterozygous genotype produces a phenotype that is a blend of the two homozygous phenotypes.

• For example, in snapdragons, red flowers (RR) crossed with white flowers (WW) result in pink flowers (RW).

• Incomplete dominance is different from co-dominance where both alleles are fully expressed in the phenotype.

• It is imp...read more
