Hemophilia is an X-linked recessive genetic disorder. A baby girl is found to have inherited the trait from her parents. What are the phenotypes of the parents?
X-linked genes are inherited. The affected girl's father is hemophilic (X-Y), and the mother might be either hemophilic (X-X-) or carrier normal (X+X-).
What are the X-linked genes?
These are the genes located in the X séx chromosome and not in the somatic ones.
Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.
According to this, X-linked genetic disorder will be inherited as well.
Men have a high probability of being affected since they only have one copy of the X chromosome. In women, the effect of the mutation might be musk in heter0zyg0us state.Hemophilia is a X-linked recessive genetic disorder.
Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.
X- is the chromosome carrying the recessive allele X+ is the chromosome carrying the dominant alleleFor the affection to be expressed, the person must be either,
X-X- ⇒ woman/girlX-Y ⇒ man/boyIf the baby girl is found to have inherited the trait from her parents, then her genotype is X-X-. She must have received one X- chromosomes from each parent.
Her father provided the X chromosome, so he must be hemophilic (X-Y)Her mother provided the other X chromosome, but she can be either a carrier (heter0zyg0us, X+X-) or hemophilic (h0m0zyg0us recessive, X-X-).Options,
Cross 1) affected father x carrier mother

F1) 1/2 = 50% of the progeny is expected to be healthy (25% X+X- girls + 25% X+Y boys)

In what areas of the world is biodiversity the lowest?
tropical regions
polar regions
temperate regions
ocean regions
Answer:
Polar regions
Explanation:
Because plants don't survive in the extreme cold and ice that cover these regions year-round.
Due to their intense and harsh environmental circumstances, polar regions like the Arctic and Antarctica often have the lowest levels of biodiversity. So, the correct option is B.
What is Biodiversity?The term "biodiversity", which is short for "biological diversity", describes the range of living things and ecosystems that exist on Earth. It includes a wide range of species, genetic diversity within those species, a wide range of environments, and a range of ecological processes. Humans benefit greatly from biodiversity as it provides them with food, medicine and ecological services such as pollination and water and air purification.
Because of their intense and harsh environmental conditions, polar regions such as the Arctic and Antarctica often have the lowest levels of biodiversity. These regions have a relatively limited diversity of species because the cold and dry conditions make it difficult for many species to live. Furthermore, these areas often have low population density due to the severe environment and scarce resources.
So, the correct option is B.

what type of cell are bacteria and archaea made of ?
Answer:
Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes, from minute spheres, cylinders and spiral threads, to flagellated rods, and filamentous chains.
Explanation:
Answer:
Prokaryotes,both bacteria and archaea have prokaryotes, which means that the cells don't have a nucleus or other membrane-bound organelles in their cells. Like bacteria, the cells have a coiled ring of DNA, and the cell cytoplasm contains ribosomes for the production of cell proteins and other substances the cell needs.

When does a zygote become an embryo?
once the embryo forms a heart, lungs, and brain
a few minutes after the male and female gamete fuse
once the zygote enters a safe environment either inside or outside of their mother
once the zygote starts dividing by mitosis and cell differentiation occurs
Answer:
Explanation:
The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome. This idea has assumed many forms. A territory in the early sea urchin blastula contains clones of founder cells, and each clone contributes exclusively to one territory (Cameron & Davidson, 1991). Both the lineage of a founder cell, i.e. its nature, and the position of a founder cell, which determines how it is nurtured, contribute to its fate. Fertilisation, the topic of the first Forum, fixes the genes; interblastomere communication, the topic here, regulates gene expression. Blastomeres communicate like any other cell – via ligand-receptor interactions and through gap junctions. Saxe and DeHaan review these mechanisms. The definition of ligands and receptors becomes broadened in this context, and cell adhesions as well as gap junctions enter into the story. In spite of these entanglements, it appears that nature uses the same sorts of mechanisms to get cells to specialise that she uses to keep them talking. Thus, neurons and glial cells signal to one another via glutamate receptors and gap junctions (Nedergaard, 1994). Likewise, we expect neurotransmitters (and neurotransmitter transporters) to help signal differentiation. The biophysicist may ask whether electrical properties also play a role, but that we reserve for another Forum. If gap junctions figure in development as fusion pores that pass small molecules and electrical signals between blastomeres, another parallel suggests itself. Brian Dale asked in the first Forum: How does a spermatozoon activate an oocyte? This question, which concerns gamete communication, has produced two schools of thought and remains controversial (Shilling et al., 1994). Do sperm activate oocytes via contact-mediated mechanisms or through fusionmediated mechanisms? Or do both mechanisms occur, as they appear to in development?
