Nov 23, 2022 · Contrary, the Y chromosome is acrocentric, contains a centromere at the end towards the p arm and contains only 2 chromatids with other usual chromosomal structural elements. Size: The X chromosome is larger in size compared to the Y, and contains 155 million bp. It covers approx. 5% part of the human genome.
Jun 20, 2024 · X and Y chromosomes are sex chromosomes that determine an individual’s sex. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). How do X and Y chromosomes differ?
Here you will learn about lines of symmetry, including symmetry properties within polygons, angle properties, and symmetry of different line graphs. Students first learn about line symmetry in grade 4 with their work with 2D shapes in geometry.
Jun 20, 2023 · During meiosis in XY males or ZW females (heterogametic sexes) the sex chromosomes pair with each other (Figure 2.5.16 2.5. 16). In mammals the consequence of this is that all egg cells will carry an X chromosome while the sperm cells will carry either an X or a Y chromosome.
In coordinate geometry, a parabola has a line symmetry and its line of symmetry passes through its vertex. For a parabola with quadratic equation y = ax 2 + bx + c, the line symmetry equation is of the form x = n, where n is a real number. The line of symmetry equation is given by, x = -b/2a.
In mammals, the sex chromosomes are called X and Y. Females have paired X chromosomes, one from each parent, while males have an X and a Y chromosome. Males get their single X chromosome only from their mothers and their Y chromosome only from their fathers.

A line of symmetry is the line that divides a shape or an object into two equal and symmetrical parts. We also call this line the axis of symmetry or mirror line because it divides the figure symmetrically, and the divided parts look like mirror reflections of each other. More line of symmetry examples are shown in the figure below.
