Answer to Problem 3RQ

Solution:

(a) Cilia

(b) Fimbriae

Explanation of Solution

The fimbriae are finger-like projections present at the end of the fallopian tube. During ovulation, the sex hormones accelerate the fimbriae and result in the inflammation. This causes a motion and allows the oocyte to release from the ovary. Cilia are present on the fimbriae and help in capturing oocyte into the uterine tube and finally toward uterus. The microvilli are minute projections that are present on the surface of the cells. The main function is in the cellular adhesion. The stereocilia are present on the hair cells.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
