Answer:
25% or 1/4
Explanation:
The gene for colour in Heliodors is controlled by two contrasting alleles that codes for Red (R) and Yellow (Y) colours. However, these two alleles exhibit incomplete dominance, which is a phenomenon whereby a combination of both alleles gives rise to a third intermediate phenotype that is a blending of the other two parental phenotypes. In this case, both colours gives rise to a heterozygous Orange coloration (RY) in Heliodors.
However, if two orange Heliodors (RY) are crossed, four possible offsprings will be produced with the genotypes: RR, RY, RY, YY. This shows a phenotypic ratio of 1 red: 2orange: 1yellow. Hence, the probability of having a child with red coloration is 1 out of 4 possible offsprings i.e. 1/4.
Expressing this in percentage, we have 1/4 × 100 = 25%.
Answer: I have no idea
Explanation: This question does not have enough information for me to answer it.
D. Cubic describes the mineral's crystal shape
Answer:
Retinitis pigmentosa often has an autosomal dominant inheritance pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. Most people with autosomal dominant retinitis pigmentosa have an affected parent and other family members with the disorder.
Explanation:
Adhesive pili, exotoxins, and capsules are all microbial factors that help them establish infection. these are examples of virulence factors.
<h3>
What is the mechanism of infection?</h3>
- Microbes encounter epithelial cells, macrophages, dendritic cells, and lymphocytes of barriers established by mucosae, mucocutaneous junctions, or skin as they enter the body through ingestion, inhalation, direct contact, cutaneous penetration, and ascending infection.
- Capsules are believed to play a part in the pathogenicity and colonization of a variety of pathogenic bacteria due to their exposure to the environment.
- Capsules can hinder host cell phagocytosis, stop complement-mediated lysis, and stop bacterial desiccation.
- Typically hear about three main categories of germs: bacteria, viruses, and fungus.
- Since most capsules inhibit water loss, they may aid in the bacterium's ability to avoid desiccation.
- A bacterial cell can be shielded by a capsule from white blood cells' digestion and obliteration.
- By inhibiting pathogen-associated molecular patterns or from binding to endocytic pattern-recognition receptors on the surface of the phagocytes, capsules can avoid unenhanced adhesion.
- Some bacteria's capsules obstruct the body's complement pathway defenses.
