Abstract

The length of the index finger (also known as the second finger or 2D finger) and ring finger (also known as the third finger or 4D finger) can be used as identifiable characteristics in humans. The relationship between the ratio of index finger length to ring finger length (2D:4D) is influenced by the hormones testosterone (in men) and estrogen (in women). Where this hormone is a hormone inherited from genes and its expression is influenced by the sex influence gene, so that there is a difference between the length of the index finger and the length of the ring finger. Estrogen and testosterone hormones that will affect the work of HOXD and HOXA in determining the length of a person's fingers. The purpose of the study was to determine the incidence of long index fingers compared to ring fingers in students and female students at SMA Muhammadiyah 1 Padang. This study shows that the difference in length between the index finger and ring finger can vary between individuals. Some studies have also found a correlation between the length of the index and ring fingers with factors such as height and genetic characteristics.

Abstract

Study this done for know variety and frequency allele decider characteristics of the face and lobes, based on There is or not lobe attached and eyebrows continued, to students at SMAN 7 Sijunjung and SMAN 1 Sungai Limau. Study carried out on 500 samples probandus (250 people from students of SMAN 7 Sijunjung and 250 students of SMAN 1 Sungai Limau ) carried out observation in a way direct with fill in data forms, as well Analyzed probandus pedigree diagram. Research result show that as many as 71.2% of SMAN 7 Sijunjung students and SMAN 1 Sungai Limau students own characteristic lobe No attached, 28.8% have characteristic lobe attached, 64.6% have characteristic eyebrow No connect and 35.4% have characteristic eyebrow connect .

Abstract

Fingerprints are one of the parts examined on dermatoglyphs. Fingerprints are images on the skin of the fingertips that are formed from the embryo and are maintained without changing. This research method uses a descriptive method with a Purposive Sampling technique which is carried out by taking fingerprint samples from students who were ranked 1-5 and students who were ranked in the bottom 5 in the class at SMA N 3 Payakumbuh and MAN 2 Agam. The percentage of students' fingerprint patterns is calculated by comparing the number of each fingerprint patterns with all the fingerprints of students at two schools with two sample group. Based on the data in Table 1, the percentage of fingerprint patterns for group of outstanding students: loop 57%, whorl 26.6% and arch 16%. Ordinary group of students with a loop percentage of 60%, whorl 26.2% and arch 13.8%. From these data it can be seen that the loop fingerprint pattern is always higher than the whorl and arch respectively sample group. This shows that with different levels of achievement, fingerprint patterns form observed fingers did not show significant differences. Even though the pattern in get both Loop patterns, but the percentage of each pattern is different.

Abstract

Fingerprints are one of the biological characteristics possessed by humans. Fingerprints consist of arch, whorl and loop pattern types. The average human has a fingerprint pattern. One individual and another individual have different fingerprint patterns and are each unique. This research method uses a descriptive method with a purposive sampling technique which was carried out by taking fingerprint samples from students who were ranked 1 to 10 from class phase f and class XII at SMA N 1 Gunung Tuleh, West Pasaman district. With a sample size of 112 people. The results of the research can be concluded that the most frequently found fingerprint patterns are loop pattern fingerprints at 71.87%, then whorl finger scale patterns at 24.48%, and arch patterns at 24.48%.

Abstract

Dendrobium is one of the genera of the third largest Orchidaceae family which reaches about 1184 species in the world. In Indonesia, this genus of orchids is a wealth of genetic resources that are abundant in the Eastern region, such as Papua and Maluku. These genetic resources have not been optimally utilized as elders in crossbreeding to produce offspring that have characteristics according to what consumers want. Due to the limitations of these morphological characteristics, another character is needed that can support the systematics of orchids, namely molecular characters. Plant kinship analysis can use molecular characters in the form of DNA strands that can overcome the weaknesses of morphological data that are known to have limitations and tend to be influenced by the environment. This study aims to analyze the kinship of several types of Dendrobium based on the rbcL gene and add to the basic data source of germplasm from the genus Dendrobium. The samples used were nucleotide sequences of 11 nucleotide sequences consisting of 10 types of Dendrobium (D. anosmum, D. jinghuanum, D. catenatum, D. nobile, D. jenkinsii, D. pahangense, D. nobile, D. pulchellum, D. fimbriatum, and D. pulchellum) which is used as an in group and 1 species of the genus Phalaenopsis namely Phalaenopsis equestris which is used as an outgroup. The results of Dendrobium kinship analysis with an in silico based rbcL gene molecular approach show that species in the same genus are not necessarily closely related. The species that is a member of the out group is Phalaenopsis equestris,. Phalaenopsis equestris forms its own tree branches, while the other 10 species are on the same phylogeny tree branches.
