Answer:
(C) maleness results from the minimal presence of one Y chromosome
Explanation:
Human males have one Y and one X chromosome as their sex chromosomes. However, the human males with Klinefelter (XXY) syndrome have two copies of X chromosome as the human males but also have one Y chromosome. Similarly, human females have two X chromosomes as sex chromosomes but the females with Turner (XO) syndrome have only one X chromosome and the females with poly-X (XXX, XXXX) have more than two X chromosomes.
This means that the Y chromosome regulates sex in human beings. If one copy of the functional Y chromosome is present in the cells, the fetus will develop into a male. The absence of a functional Y chromosome will make the fetus develop into a female.
Chicken is one of the fowl and it is one of the widespread and well-known fowl. It is found in almost all area.
<u>Explanation:</u>
<u>1.Observations of the chicken leg dissection.</u>

<u>3.Characteristics of muscles in movement</u>
- The characteristics of muscles help us determine the direction of the movement are the biceps and the triceps muscles are used in the wings for the movement and the tendons attach these muscles to the bone
Gametes, or sperm and egg cells are both haploid cells, meaning that they have half the amount of chromosomes that regular body cells do, meaning that the sperm cell of this bird would have 32 chromosomes.
From the options given above, the correct option is D. A haploid cell is a cell that contains a single set of chromosomes only. A haploid cell can only undergo asexual reproduction. Asexual reproduction involves only one parent and the cell division usually occurs by mitosis. An organism that is reproducing asexually will transmit 50% of its gene to its offspring[s]. Thus, haploid cells reproduce asexually through mitosis only.
