Please help with my biology

Substitution

Explanation:

Deletion would be deleting (C)

Insertion would be inserting another letter

C. Substitution

Explanation:

Mutations occur when a gene sequence is changed in one way or another. In this case, the 6th base, C, was swapped with an A. This is a substitution mutation where one base is substituted for another. An easy way to tell this is substitution is that the number of bases does not change in the mutated sequence.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

i think its white blood cells

i hope this
