Some types of muscular dystrophy are X-linked recessive disorders. A mother who is a carrier for muscular dystrophy has children with a father who doesn’t have muscular dystrophy.
a. What percentage of their sons will have the disease, and what percentage of their sons will be carriers?
b. What percentage of their daughters will have the disease, and what percentage of their daughters will be carriers?

Show your work with a Punnett Square, using XD to represent the allele not associated with muscular dystrophy and Xd to represent the allele associated with muscular dystrophy. You can copy/paste the blank table below or create a table in the submission box to complete the Punnett square.

Answers

D gene is an X-chromosome-linked gene. a) 100% will have the disease, XdY // 0% will be carriers. b) 0% will have the disease // 100% will be carriers, XDXd.

What are the séx-linked genes?

These are genes that can be found only in the X-chromosome. The inheritance pattern expressed by these genes varies from the one expressed by genes located in autosomal chromosomes.

In the exposed exampe,

- muscular dystrophy are X-linked recessive disorders

- woman ⇒ carrier for muscular dystrophy ⇒ heter0zyg0us ⇒ XDXd

- man ⇒ doesn’t have muscular dystrophy ⇒ X-chromosome with the dominant allele ⇒ XDY

- XD ⇒ chromosome rarrying the dominant allele

- Xd ⇒ chromosomes carrying the recessive allele

What is Crossing over and DNA replication

Crossing over involves the swapping of genetic materials, and it occurs in prophase I of meiosis before meiosis II the crossing over of genetic materials are over. while DNA replication is the process whereby DNA make an exact copy of itself during the process of cell division and this process occurs prior to meiosis I and meiosis II

B. A neuron synapses with another neuron via a neurotransmitter.
C. Eye muscles constrict in response to light.
D. Secretion of TSH stimulates the secretion of thyroxine.
E. The maternal parent induces spontaneous expression of recessive genes.

Answers

Answer:

A

Explanation:

A

How does the ectoderm that will make up the future eye know to develop into an eye? The cells are "told" to develop into an eye because the nearby retina releases chemical signals that direct the development of the cells. This process is called induction. Choice A depicts a similar situation. The notocord releases chemical signals that tell the overlying ectoderm that it is time for it to become the neural tube. None of the other choices depict the process of induction.

form and function are related. describe how the form of the tracheal wall is related to its four functions

Answers

Given what we know we can confirm that the tracheal wall is related to its function in that it allows it to conduct air in a sealed manner and protect the individual.

What is the function of the trachea?

The primary function of the trachea is to conduct air into the lungs. For this, the trachea is long and narrow, to allow air to flow in a directed manner towards the lungs. The trachea is also "armored" to protect this air flow and is lined with mucus to sweep away any unwanted particles from the air.

Therefore, we can confirm that the trachea is armored and lined with mucus along its long, tube-like shape, which allows this structure to conduct air in a safe, clean, and direct manner directly towards the lungs.

Explanation:

When sperm and eggs in plants are united they fertilize the egg creating a plant able ready seed. Some factors in an environment that help them unite are; (animals) bees, butterflies, and other insects. wind bringing pollen around

When sperm and egg (found in different parts of plant) unite fertilization takes place which results in the formation of a zygote and later it forms an embryo.

Some factors in an environment that help unite them are air, water, insects, birds, bats etc.

What is sperm?

"Sperm is defined as male reproductive cell. In case of plants, it is known as male gametophyte (pollen)."

What is egg?

"Egg is defined as female reproductive cell. In case of plants, it is known as female gametophyte (ovum)."

What is fertilization?

"Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote."

In pea plants, petal coloration of has a complete dominance relationship where purplepetals are dominant over white petals. There are 276 plants, 273 have purple petals.Find: the frequency of the dominant and recessive alleles and the frequency ofindividuals with the dominant, heterozygous, and recessive genotype.

Answers

Answer: See below

Explanation:

In the selected pea plant population, there are total 276 plants out of them 273 have purple petals.

Remaining 276 - 273 = 3

q²= 3/276

q²= 0.010

q = 0.1

p + q = 1

p = 1 - 0.1

p = 0.9

Therefore:

Homo-zygous dominant = p² = 0.9×0.9 = 0.81

Hetero-zygous dominant = 2pq = 2×0.9×0.1 = 0.18

Homo-zygous recessive = q² = 0.1×0.1 = 0.010

HELP, define genetic engineering and Describe how DNA is modified for use in genetic engineering.

Answers

Answer:

Genetic engineering is deliberate modification of genome to gain desired traits.

The main steps of genetic engineering:

Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.
