Traits that are determined by a single gene are of five main types: y-linked, x-linked dominant, x-linked recessive, autosomal dominant, and autosomal recessive. how many of these modes of inheritance are possible for this pedigree? assume the gene is completely penetrant, and there is no new mutations.

For the Y-linked gene, there is only one mode of inheritance. For X-linked dominant and recessive genes, there are two modes of inheritance. For the autosomal dominant and recessive, it depends on the origin of the genes. For homozygous dominant and homozygous recessive parents, there is only one mode of inheritance.

Autosomal dominant is the only fit for inheritance, considering that it a person will be able to inherit a condition from the parent. And since there is no mutation in it, a NEW mutation can happen in the genes even though there is no history of it in the family.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
