  • what statistical test should I use?

    A. the data from 18 past kentucky derby is shown with the winning horse and its sire (father) and the mean pre-derby price of each sire's offspring and a mean post-derby price for offspring. Does siring of the winner of the kentucky derby change the mean offspring price from pre-derby to post-derby?

    What statitical test would I run in SPSS?

    B. What test would I run if I wanted to determine if there was a relationship between pre-derby and post-derby price

    C. Use the pre-derby price to predict the post derby price (what test?)

    I was thinking Pearson r and a linear regression maybe?

  • My boyfriend loves me but is having doubts about our relationship?

    My boyfriend and I are very much in love and have been for a while. I love him so much. We recently got into an argument about sex, because I'm concerned why he doesn't seem interested in having sex with me anymore. He explained that he just doesn't need it everyday and I needed to relax. (This was last week) We had another talk tonight and he said he honestly isn't interested in having sex, and that it wasn't because I'm not attractive or he doesn't want to have sex with me at all, but that he's just not really interested except maybe sometimes (he's 22 and this lack of sex/loss of interest has happened in the last month or so).

    I then asked him if he still saw us getting married and having kids in the near future (like we have talked about for months with out having a single doubt) and he said he didn't know anymore. That he's confused and worried about us (but he says he doesnt know why) and he doesn't know how he feels anymore except that he loves me and doesn't want to loose me and does not want to break up. I'm so scared about our relationship. I do not want this to end. He is the one for me and it terrifies me when he says he doesn't know. Especially when he said that before all of this happened he would have said yes to the marriage/kids question without a doubt.

    I desperately need some advice. Or some guidance. Please help.

  • My boyfriend seems uninterested in me/sex?

    I've been with my boyfriend for a while now and we very much love each other. We lost our virginity to one another, and in the beginning we had great sex very often and now we have had sex maybe once in the last month and a half (and it was awful). I ended up talking to him about it an his obvious lack of interest in sex with me and he just said that I want it too much and he just wants to "be" with me like we used to. He said he doesn't need sex all the time and I needed to stop (i love having sex and i dont know what i need to stop) Obviously from my point of view I'm hurt and feel unattractive and not wanted. I've tried initiating and he simply tells me he's not in the mood or he's too tired. I've bought sex toys and lingerie to excite him and have gotten no reaction out of him. It's hard being in a relationship when you feel unwanted and unattractive. I feel like, at least from my perspective, our relationship is becoming strained because of this. I don't know what more I can do. This little part of our relationship is destroying my self esteem.

  • My boyfriend can't orgasm?

    My boyfriend can't ejaculate. He can have dry orgasms but no matter what we do he can't ejaculate. He says he can't do it by himself either. He told me he hasn't ejaculated in 3 months. Every time we try he gets really close but never is able to get it all the way. Is there something wrong with him? Should he see a doctor? We are starting to get really worried.

  • Genetics help please?

    In silkmoths (Bombyx mori), red eyes (re) and white-banded wing (wb) are encoded by two

    mutant alleles that are recessive to the wild-type traits black eye (re+) and unbanded wing (wb+);

    these two genes are on the same chromosome. A graduate student has two different lines of

    moths, A and B, that both show the wild-type traits (black eye and unbanded wing). He is unsure if

    the two lines are heterozygous for either or both traits, and whether they have the same allele

    linkage arrangements. He testcrosses females from each line with red eyed, white-banded wing

    males and obtains the following progeny:

    Progeny of:

    Phenotype A females, B females

    wild type 418, 8

    red eye 16, 210

    white-banded wing 19, 216

    red eye, white-banded wing 426, 9

    a) Explain whether these lines of moths (A and B) are homozygous or heterozygous for both

    characteristics (eye color and wing banding), and why different proportions of progeny are

    produced when each of the lines A and B are testcrossed.

    '

    b) Give the genotypes of moths A and B, indicating the linkage arrangement of the alleles on the

    homologous chromosomes in each case (i.e., coupling or repulsion).

    c) Determine map distance

  • Genetics problem help?

    Please help with this problem! I'm pretty lost on how to do it

    The following X-linked recessive alleles are found in fruit flies: vermillion (v) eyes are recessive

    to wild-type eyes, miniature wings (m) are recessive to wild-type wings, and sable body color (s) is

    recessive to wild-type body color. A cross between a female with vermillion eyes, miniature

    wings, and sable body and a male wild type for all three genes produced an F1 with wild-type

    females and males with vermillion eyes, miniature wings and sable body. The F1 females and

    males were then crossed, and the following F2 progeny were produced:

    vermillion, miniature, sable 1320

    wild type 1346

    vermillion, miniature 102

    sable 90

    vermillion 42

    miniature, sable 48

    vermillion, sable 2

    b) Give the relative order of these genes on the X chromosome.
