Comparison of fundamental asymmetry of sex and sexual dimorphism between the two-monkey species. Introduction: According to the Bateman–Trivers hypothesis, two processes are involved namely pattern and process. In this, the pattern refers to the trait, which attracts the members of the opposite sex and it is highly expanded in the males. In the process, high energy expense is required for the formation of large egg, whereas the sperms contain few energetic resources . Consequently, females in most species invest more in their offsprings in comparison to males. During study of several species of monkeys in one case, males never helped females to raise offspring. While in another case, males provided just as much parental care as females except for actually carrying the fetus during pregnancy.

Comparison of fundamental asymmetry of sex and sexual dimorphism between the two-monkey species.

Introduction:

According to the Bateman–Trivers hypothesis, two processes are involved namely pattern and process. In this, the pattern refers to the trait, which attracts the members of the opposite sex and it is highly expanded in the males. In the process, high energy expense is required for the formation of large egg, whereas the sperms contain few energetic resources. Consequently, females in most species invest more in their offsprings in comparison to males.

During study of several species of monkeys in one case, males never helped females to raise offspring. While in another case, males provided just as much parental care as females except for actually carrying the fetus during pregnancy.

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…
