[Tex/LaTex] How to tab the whole subitem

enumitemindentationlists

I'm typing up a document that requires subitems (ex: 1. a), b), etc.). I have been able to do this by using \subitem but what really bugs me is that only this first line of the subitem has a indent (tab) and what follows after does not conform to that indent. Does that make sense? Here's a picture of what I'm talking about in case it doesn't:

I tried using \setlength{\parindent}{0.25cm} but that didn't work. I am using the enumitem package, but I haven't looked into it very throughly so maybe there's something there that I haven't tried. I would really appreciate if anyone has any suggestions as to how to resolve this semi-annoying problem. Thanks in advance!

EDIT The code I'm using (a portion of it):

\item \textit{CC DD} and \textit{cc dd} individuals were crossed to each other, and the $\mathrm{F_{1}}$ generation was backcrossed to the \textit{cc dd} parent. 903 \textit{Cc Dd}, 897 \textit{cc dd}, 98 \textit{Cc dd}, and 102 \textit{cc Dd} offspring resulted. 

\subitem a. How far apart are the \textit{c} and \textit{d} loci?

\subitem b. What progeny and in what frequencies would you expect to result from testcrossing the $\mathrm{F_{1}}$ generation from a \textit{CC dd} X \textit{cc DD} cross to \textit{cc dd}?

Just embed one enumerate environment in another:

\documentclass{article}
\usepackage{lipsum} % just for some dummy text
\usepackage{enumitem}
\setenumerate[2]{label=\alph*.}
\begin{document}
\begin{enumerate}
\item
\begin{enumerate}
\item \lipsum[1]
\item \lipsum[2]
\end{enumerate}
\item \lipsum[3]
\end{enumerate}
\end{document}

[Tex/LaTex] Need itemize list items without using a list

This may be what you want, with help from @ChristianR and from
change the itemize from bullet to square

 \documentclass{article}

\newenvironment{notalistitem}
{\begin{itemize}
\renewcommand{\labelitemi}{$\triangleright$} 
\item}
{\end{itemize}}

\begin{document}

Some text

\begin{notalistitem}
Here is text that should look like a list item although it doesn't
seem to be part of a list.
\end{notalistitem}

\begin{itemize}
\item This is part of a list.
\end{itemize}

\end{document}

Edit: You'll need something more robust if you want to use an itemize inside this new environment, or one of these inside an itemize.

[Tex/LaTex] Subitem in enumerate written as . instead of indentation

You should set leftmargin=0pt for the inner list. I suggest defining your own environment also for the outer list. There is no need for \originall@bel, but an \ignorespaces is needed.

\documentclass{article}

\usepackage{lipsum}
\usepackage{enumitem}
\usepackage{etoolbox}

\newlist{reqs}{enumerate}{1}
\newlist{subreqs}{enumerate}{1}
\setlist[reqs]{label=R~\arabic*,widest*=100,leftmargin=*}
\setlist[subreqs]{label=\thereqsi.\arabic*,leftmargin=0pt}

\makeatletter
\newcommand*{\req}[1]{%
  \item 
  \appto\@currentlabel{ (#1)}%
  \emph{#1}\quad\ignorespaces}% <--- note \ignorespaces
\makeatother

\begin{document}

\lipsum[3]
\begin{reqs}
\req{First Important Thing} \label{req1} \lipsum[4]
\begin{subreqs}
\req{Important Subitem} \label{req2} \lipsum[2]
\end{subreqs}
\end{reqs}
\lipsum[3]

\ref{req1} and \ref{req2} are important.

\end{document}

If you want left alignment of the labels, you can pass the label width of the outer environment to the inner one:

\documentclass{article}

\usepackage{lipsum}
\usepackage{enumitem}
\usepackage{etoolbox}

\newlist{reqs}{enumerate}{1}
\newlist{subreqs}{enumerate}{1}
\setlist[reqs]{
  label=R~\arabic*,
  widest*=100,
  leftmargin=*,
  align=left,
  before=\edef\outerlabelwidth{\the\labelwidth}
}
\setlist[subreqs]{
  label=\thereqsi.\arabic*,
  leftmargin=0pt,
  labelindent=0pt,
  labelwidth=\outerlabelwidth,
  align=left,
}

\makeatletter
\newcommand*{\req}[1]{%
  \item %
  \appto\@currentlabel{ (#1)}%
  \emph{#1}\quad\ignorespaces}
\makeatother

\begin{document}

\lipsum[3]
\begin{reqs}
\req{First Important Thing} \label{req1} \lipsum[4]
\begin{subreqs}
\req{Important Subitem} \label{req2} \lipsum[2]
\end{subreqs}
\end{reqs}
\lipsum[3]

\ref{req1} and \ref{req2} are important.

\end{document}
