Question
Chapter 40.4, Problem 2LO
Summary Introduction
To describe: The three evolutionary strategies that promote outcrossing.
Introduction: The plants are the multicellular eukaryotic organism in the kingdom Plantae. It is characterised by photosynthetic nutrition, a process through which it synthesis carbohydrates, essential unlimited growth at localised region, presence of cellulose in their cell wall and absence of locomotory organs.

- The Soay sheep of St. Kilda Island near Scotland have changed coat color over the past 20 years, with dark colored sheep declining in frequency and light colored sheep increasing. Coat color is determined by the TYRP1 gene. The TYRP1-T homozygote is light colored, while TYRP1-G homozygotes and heterozygotes are dark. Discuss the hypothesis that assortative mating between sheep with similar coat color is the cause of the increase in light coat color over this period.arrow_forwardArginine yasotocin (AVT) is a hormone implicated in reproductive function in fish. In a study investigating the role of AVT on mating success, a 4th year student performed a series of crosses to assess the effects of different alleles of the AVT gene (WT and ayt-) on mating success. The following figure provides the results of 4 different crosses. 100 E 80- 60 40 – 20 – O wt X ơwt ?
