Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
<h2>Anatomy of Aorta</h2>
Explanation:
- The protein elastin is found in connective tissues all through the body. It is eminently found in the extracellular lattice of the skin just as the inward organs of the body. The name elastin sounds a lot of like 'flexible.' This is no fortuitous event. The elastin protein is adaptable and gives numerous tissues their versatility.
- Inferable from its exceptional capacity to extend and withdraw, the aorta additionally fills in as a store that changes the profoundly compelled and pulsatile heart yield into a progression of moderate variances.
- The tunica intima comprises of a solitary layer of ECs that lines the lumen of the vein and is moored to the fundamental cellar film, an exceptionally particular ECM organize comprising basically of laminin, collagen type IV, fibronectin, perlecan, and heparan sulfate proteoglycans.
- This storm cellar layer additionally assumes a vital job in flagging occasions that direct EC movement, intrusion, expansion, and survival. The cellar film together with the inward flexible lamina (IEL) fills in as an interface between the tunica intima and tunica media.
Answer:
the the climax of the night
To test the effectiveness...
A. This variable should be controlled (the same in both groups).
B. The new chemical is what is being added to the experimental group.
C. This is the control group to which the treated couch should be compared.
D. This is the experimental group to which data should be taken.
Final answer: D
