Consider the following information.
In fruit flies, dominant gene "R" produces red eyes and recessive gene "r" produces white eyes. Also, the R and r alleles are sex-linked (they are part of the X chromosome but not the Y chromosome or the autosomes). Pick the correct mating described by the following questions.
A. Rr x R- mating
B. RR x r- mating
C. rr x R- mating
D. Rr x r- mating
E. rr x r- mating
In females an entire X chromosome is inactivated in each cell. The inactivated X chromosome ensures __________.
A. You have 23 pairs of chromosomes. Within those chromosomes are the various genes that encode for all the necessary proteins for your body. Those genes are made up of DNA.
C. The nitrogen containing bases (ATP, GTP, CTP, TTP) are nucleoitdes which code for an ...
