So, one at a time: I'm attaching a picture of the punnet squares (hard to make on the computer (and you can simplify the ratios down):
4. HHnn x hhNN
All offspring are HhNn; 100% same genotype (HhNn); 100% phenotype of short, normal
5. HhNn x HhNn
Genotypes and ratio:
HHNN(1): HHNn(2): HhNN(2):HhNn(4):HHnn(1):Hhnn(2): hhNN(1):hhNn(2):hhnn(1)
Phenotypes and ratio:
Short normal (9): short colorpoint(3):Long normal (3): Long colorpoint (1)
6. TtNn x ttnn
Genotypes and ratio:
TtNn(4):Ttnn(4):ttNn(4):ttnn(4) (which is 1:1:1:1)
Phenotypes and ratio:
Tabby normal (1): Tabby colorpoint (1): Stripless normal (1): stripless colorpoint (1)
7. hhNn x hhNn
hhNN(4): hhNn(8):hhnn(4)
short normal (12): short colorpoint (4)
Answer:
The correct answer would be a deletion mutation.
Deletion mutation is a type of mutation in which a sequence of DNA gets lost during the replication process.
The length of a lost sequence may vary from a single nucleotide to the entire length of a chromosome.
It can also be caused by errors during crossing over that takes place in meiosis I.
A deletion that does not occur in multiples of three nucleotides can result in frame-shift mutation.
Similarly, in the given sequence ATGC, guanine is deleted which results in the formation of a new reading frame that is, ATC.
The body size of this population of iguanas correlate with algae height because <span>Traits are exchanged between iguana and algae populations so that taller algae result in larger iguana populations. hope this helps</span>
Answer:
Explanation:
Sweating is a form of homeostasis which helps to maintain a balance in the body's internal environment. However, when the air in the external environment (air temperature) is of a high temperature, sweating increases so as to help your skin cool off as a result of the evaporation of the sweat. This is also the same reason one does not sweat much when the air temperature is low; the skin is already been cooled by the environmental air temperature and as such sweating is reduced in cases like this except the body is trying to release excess water (which would ordinarily go through urine during this situation but the individual might still sweat if the person refuses to urinate on time).
