Lecture 5 Flashcards
Mitochondrial and chloroplast genes are inherited from the female parent (from the egg cell during fertilization). Why?
The reason for this is because the size comparison between the female egg and male sperm is drastically different. The egg can carry much more genetic information and organelles, the sperm already has a hard enough time carrying its own genetic material.
A mode of uniparental inheritance from the mother is called ______________. Fill in the blank.
maternal inheritance
How are mitochondrial genes inherited?
Mitochondrial genes are not inherited through chromosomes they are inherited through mitochondrial (uniparental inheritance (1 parent)
Most mitochondrial genes encode proteins that are part of your ATP synthase and the protein complexes of the electron transport chain. If these are mutated or damaged, it can affect your nervous system and metabolic functions. For example, _________________ can be caused and result the optic neuron degeneration over time. Fill in the blank.
Leber’s Hereditary Optic Neuropathy
How are chloroplast genes inherited?
They are uniparental and can only be inherited from the female plants.
According to the video Multiple Alleles (ABO Blood Types) and Punnett Squares, what happens if you try to give a B-antigen person (a) A-antigen, (b) AB-antigen, or (c) O-antigen blood?
If you try give a B-antigen person A or AB-antigen the immune system won’t recognize the antigen and attack it. If you try give a B-antigen person O-antigen it would be safe because it doesn’t have A or B antigens.
According to the video Multiple Alleles (ABO Blood Types) and Punnett Squares, why can O-antigen blood only receive donated blood from an O-antigen individual?
O-antigen blood only receive donated blood from an O-antigen individual because O blood doesn’t have any antigens.
According to the video Multiple Alleles (ABO Blood Types) and Punnett Squares, which blood type is a universal acceptor? Why?
The blood type that is a universal acceptor is AB because they have both the A and B-antigen.
According to the video Multiple Alleles (ABO Blood Types) and Punnett Squares, what does it mean your blood is + or – ?
If the blood is positive it means you have the Rh factor, if the blood is negative that means you don’t have the Rh factor.
