Sex Traits

Abstract Drosophila crosses laboratories 8, 11 and 13 to explain how sexually related genes are inherited from one generation to the next. This is accomplished by crossing different genotypes. To do this, flies are allowed to sleep first, then counted within the anatomical structure, and finally to red-eye women, white-eyed women, red-eye men, and white-eyed men It has to be divided. In the F1 generation, my results were 22 red - eye men, 0 white - eye male, 47 red - eyed women, 0 white - eyed women.

The sexual linkage trait is a genetic feature determined by genes located in the sex chromosome. Since gender-related traits are handed down from parent to descendant, each parent inherits characteristic alleles. Genes found on sex chromosomes are called sex - linked genes. The gene located on the Y chromosome is a Y linked gene which is inherited in men only when the male has XY chromosome. Genes located on the X chromosome are X linked genes and they all contain the X chromosome, so they can be inherited by both women and men. If one allele is dominant and the other is recessive, the dominant trait is expressed beyond the recessive trait and the recessive trait is concealed. However, with X linked genes, the recessive trait of men will be expressed as a man containing only one X chromosome and not including the dominant nature overwhelming the recessive trait. For example

Human chromosomes are divided into two types, autosomes and sex chromosomes. Because some genetic traits are related to human sex, it is transmitted by sex chromosomes. The autosomes contain the remaining human genetic information. All humans have 23 pairs of chromosomes in which these genetic material is developed, of which 22 pairs are autosomal and the remaining pair (XX, female or XY, male) represents human sex chromosome . These 23 pairs of chromosomes will help together to create the people we will ultimately become.

Everyone is composed of cells, each containing a chromosome. Chromosomes are genetic material that determines a lot of people's things, such as the color of eyes and hair, biological gender, personality characteristics. DNA or deoxyribonucleic acid is involved in the spread of genetic material. At the moment of pregnancy, mother and father DNA will be inherited. Humans have 23 pairs of chromosomes. A growing fertilized ovum acquires half of the chromosome from one parent and half of the chromosome from the other parent. The first 22 pairs of chromosomes are called autosomes and determine the color of eyes and hair. The last pair, called sex chromosomes, determines the physical sex of a person. Females have two X chromosomes, and men have X and Y chromosomes.
