Explanation:
<span>A mutagen is a physical or synthetic operator that progressions the hereditary material, normally DNA, of a creature and along these lines expands the recurrence of transformations over the regular foundation level. Mutagens can be physical or chemical that should increase the mutation rate.</span><span />
Answer:
Carotenes are less polar and would elute first.
Explanation:
Carotenes are organic compounds like chlorophyll, they are responsible for the orange color in carrot. So, while chlorophyll is green, carotene is orange in color.
In terms of structure, carotene is a hydrocarbon (made up of carbon and hydrogen chains), making it non-polar. On the other hand, chlorophyll (made up of carbon, hydrogen, oxygen, nitrogen, magnesium) is more polar.
Chromatography is a separation technique used to separate two or more mixtures. The working principle is based on how fast each solute travels. So in column chromatography, the components of the mixture travel through a column (e.g a burette) at different speed. The less polar component travels faster.
So far a mixture of carotene and chlorophyll, the less polar carotene will travel faster than the more polar chlorophyll. Therefore, carotene will elute first.
Answer:
The phenotypes will be -
AaBbcc - Albino,
AaBBCC - Agouti Black
Aabbcc - Albino
AAbbCc - Agouti Brown
aaBbCc - Solid color, Black
AABBcc - Albino
Explanation:
The C/c gene is epistatic to both the A/a and B/b genes, any offspring with the cc allele combination will be albino. Otherwise, the A/a and B/b genes are expressed normally.
