Biology Do as Directed.

Known as sex-chromosome, determine an individual's sex.

Responsible for physical character of progeny.

Carries parental characters to offspring.

Carries genes which carry information to be transfered to the offsprings from the parents.

Genetic material in living organism, controls biosynthetic processes of cell.

X-linked Inheritance, Carrier Female, Affected Male, Genetic Transmission, Trait Expression
Explanation:
In X -linked inheritance, a female can be a carrier without showing symptoms, while a male, having only one X chromosome, is more likely to be affected. The genetic transmission from a carrier female to her offspring determines the expression of the trait, especially in male progeny.

Dihybrid Cross, Law of Independent Assortment, Gene, Variation, Phenotype
Explanation:
In a Dihybrid Cross, two traits are studied together. The Law of Independent Assortment states that genes for separate traits are inherited independently, ensuring that one trait's inheritance doesn't impact the other. This mechanism fosters genetic variation in offspring, manifesting in diverse phenotypes or observable characteristics.

Law of Segregation, Allele, Gametes, Genotype, Phenotype
Explanation:
The Law of Segregation states that alleles separate during gamete formation, so each sperm or egg carries only one per trait. Upon fertilization, these gametes form an organism's genotype, which dictates its phenotype - the visible traits. This law says the inheritance of traits and the resulting diversity in offspring.

Dihybrid Cross, Allele, Dominant, Recessive, Variation
Explanation:
In a Dihybrid Cross, which involves two different traits, the first consideration is the alleles for each trait. Alleles can be either dominant or recessive, with dominant alleles overshadowing the effects of recessive alleles. The combination of these alleles leads to variation in the offspring, resulting in diverse phenotypic expressions of the two traits being studied.

Gene, Base pairs, DNA, Chromatid, Centromere
Explanation:
A gene is a segment of DNA which is composed of base pairs. A DNA molecule forms the structure of a chromatid. Chromatids are joined together at a centromere to form a chromosome

DNA double helix, Nucleotide, Chromatin, Histone, Chromosome
Explanation:
The DNA double helix is composed of nucleotides. Chromatin is made of DNA wrapped around histone proteins. This chromatin further condenses to form chromosomes during cell division.
