In a population of 1000 fruit flies, 360 have red eyes and the remainder have sepia eyes. The sepia eye trait is recessive to re

d eyes. How many individuals would you expect to be homozygous for red eye color if the population is in Hardy-Weinberg equilibrium?

Answer:

<h2>40</h2>

Explanation:

Calculations:

Let q²= homozygous recessive

p²=  homozygous dominant  

2 pq heterozygous

q² for this population is 640/1000 = 0.64

q = √o.64 = 0.8

so, P= 1- q  

= 1- 0.8 = 0.2

The homozygous dominant frequency = p² = (0.2)(0.2) = 0.04

Therefore, you can expect 4% of 1000, or 40 individuals, to be homozygous dominant.

DESCRIBE the internal anatomy of skeletal muscle, using each of the following terms: ACTIN, MYOSIN, THIN FILAMENT, THICK FILAMEN
jasenka [17]

INTERNAL ANATOMY OF SKELETAL MUSCLE : SKELETAL MUSCLE IS OTHERWISE CALLED AS STRIATED OR VOLUNTARY MUSCLE. THEIR ACTIVITIES ARE UNDER THE VOLUNTARY CONTROL OF NERVOUS SYSTEM. THEREFORE, THEY ARE KNOWN AS VOLUNTARY MUSCLES. PRIMARY FUNCTION OF THIS MUSCLE IS LOCOMOTION AND CHANGES IN BODY POSTURE.

EACH MUSCLE IS MADE UP OF NUMBER OF MUSCLE BUNDLES OR <u>FASCICLES</u>. THESE FASCICLES ARE HELD TOGETHER BY A COMMON COLLAGENOUS CONNECTIVE TISSUE LAYER CALLED FASCIA.

EACH MUSCLE IS COMPOSED OF NUMEROUS MUSCLE FIBRES AND IT IS MULTINUCLEATED, CROSS STRIATED CYLINDRICAL CELLS. IT IS MADE UP OF SARCOLEMMA OR CELL MEMBRANE ENCLOSING SARCOPLASM (CYTOPLASM) . NUMBER OF EVENLY DISTRIBUTED LONGITUDINAL THREADS CALLED <u>MYOFIBRILS</u> ARE PRESENT IN THE SARCOPLASM.

MUSCLE-FASCICULE-FIBRE-MYOFIBRILS-MYOFILAMENTS

EACH MUSCLE IS AN INDIVIDUAL CELL AND CONSISTS OF FOLLOWING PARTS.

SARCOLEMMA,  SARCOPLASM, NUCLEI,  MYOFIBRILS, MYOFILAMENTS, MITOCHONDRIA, SARCOPLASMIC RETICULUM.

SARCOLEMMA IS CELL MEMBRANE OF MUSCLE FIBRES AND SARCOPLASM IS SEMIFLUID CYTOPLASM OF MUSCLE.

NUCLEI ARE MULTIPLE IN NUMBER AND OVAL IN SHAPE, PERIPHERAL IN DISTRIBUTION BENEATH THE SARCOLEMMA.

<u>MYOFIBRILS</u> ARE CONTRACTILE UNBRANCHED THREADS SITUATED ALONG THE MUSCLE FIBRE.  IT CONSIST OF ALTERNATE A-BAND

AND I-BAND. EACH MYOFIBRILS CONSISTS OF LONGITUDINALLY ARRANGED PROTEIN FILAMENTS SUCH AS <u>THIN FILAMENT</u> CONSISTS OF <u>ACTIN,</u> TROPOMYOSIN, TROPONIN WHEREAS<u> THICK FILAMENT</u> CONSISTS OF<u> MYOSIN</u> . THESE ARE CALLED MYOFILAMENTS.

MITOCHONDRIA PROVIDES ENERGY FOR THE WORK OF  MUSCLE FIBRE.

BESIDES THE ABOVE COMPONENTS THERE ARE THREE TYPES OF SUPPORTING TISSUES WHICH HELPS IN ORGANIZATION OF SKELETAL MUSCLES. THESE ARE.

<u>ENDOMYSIUM</u> : IT IS A DELICATE SHEATH OF CONNECTIVE TISSUE WHICH COVERS EACH MUSCLE FIBRE OUTSIDE THE SARCOLEMMA.

<u>PERIMYSIUM</u> : THE MUSCLE FIBRES ARE GROUPED INTO FASCICULI EACH FASCICULUS IS COVERED BY A CONNECTIVE TISSUE SHEATH CALLED PERIMYSIUM.

<u>EPIMYSIUM</u> : THE ENTIRE MUSCLE IS COVERED BY A SHEATH OF CONNECTIVE TISSUE KNOWN AS THE EPIMYSIUM.

¿A qué se refiere la sexualidad libre de coerción y violencia?
kozerog [31]

Para las mujeres y las niñas, el derecho a controlar su propio cuerpo y su sexualidad sin ningún tipo de discriminación, coerción o violencia es fundamental para su empoderamiento. Sin derechos sexuales, no pueden realizar sus derechos a la autodeterminación y la autonomía, ni pueden controlar otros aspectos de sus vidas. De hecho, son los intentos de controlar la sexualidad de las mujeres y las niñas los que dan como resultado muchos de los abusos de los derechos humanos que enfrentan a diario, incluida la violencia de género, el matrimonio forzado, la mutilación genital femenina y limitaciones en su movilidad, vestimenta y educación. , empleo y participación en la vida pública. Lo mismo ocurre con las lesbianas, los hombres gay, las personas bisexuales, las personas transgénero, las trabajadoras sexuales y otras personas que transgreden las normas sexuales y de género y que, como resultado, enfrentan un mayor riesgo de violencia, estigma y discriminación. Está claro: los derechos sexuales sustentan el disfrute de todos los demás derechos humanos y son un requisito previo para la igualdad y la justicia.

A nivel mundial, existe un gran debate sobre si definir los derechos sexuales y cómo hacerlo. IWHC cree que para superar algunas de las barreras políticas al reconocimiento, respeto, protección y cumplimiento de los derechos sexuales, necesitamos aclarar cuáles son.

IWHC, en colaboración con otras organizaciones líderes de derechos humanos y salud sexual, ha desarrollado la siguiente definición de trabajo de derechos sexuales:

Los derechos sexuales abarcan ciertos derechos humanos que ya están reconocidos en las leyes nacionales, documentos internacionales de derechos humanos y otros documentos de consenso. Se basan en el reconocimiento de que todas las personas tienen derecho, libres de coerción, violencia y discriminación de cualquier tipo, al más alto nivel posible de salud sexual; perseguir una vida sexual satisfactoria, segura y placentera; tener control y decidir libremente, y con el debido respeto a los derechos de los demás, sobre asuntos relacionados con su sexualidad, reproducción, orientación sexual, integridad corporal, elección de pareja e identidad de género; ya los servicios, educación e información, incluida la educación integral en sexualidad, necesarios para ello.
