Determine the correct order of the genes on the chromosome, given the following information: Genes A and T cross over at a rate of 18% Genes M and T cross over at a rate of 9 % Genes A and H cross over at a rate of 11% Genes M and H cross over at a rate of 2% a. TMAH b. AMHT c. MATH d. TAMH

b. AMHT

Explanation:

The arrangement of genes on a chromosome can be estimated by considering the distance between the genes using the rate or frequency of their cross overs. Therefore, we have:

A18T

                        M9

11H

                          ---2---

Thus, using the arrangement above by selecting the letters as they occur, we have:

AMHT as the correct genes arrangement in the chromosome.

the answer is c) an oak tree

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.
