The correct answer is explained below:</h2>
Explanation:
- According to the question, free ear lobes are dominant over attached ear lobes.
- Let the allele for free ear lobes be represented by F.
- Let the allele for attached ear lobes be represented by f.
- The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
- The gamete produced by the woman is: f.
- The genotype of the heterozygous man (father) with free earlobes is: Ff.
- The gametes produced by the man are: F and f.
- Mating the man with the woman we get the following offspring,
F f
f Ff ff
Phenotype Free ear lobe Attached ear lobe
- The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
- The probability that the parents would produce children with attached ear lobes is = .
Answer:
B. F1
Explanation:
Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
Answer:
The process in which energy is emitted by one object, transmitted through space, and absorbed by another.
Explanation:
So let's think about what convection means: movement in a liquid where the hotter part moves through the cooler part.
So by have the definition of the convection which one of the descriptions best fits the definition?
Answer:
Both will be equal to one another
Answer:
31 pairs
Explanation:
Peripheral nervous system composed of neurons outside the brain and spinal cord while the central nervous system is composed of brain and spinal cord. The peripheral nervous system connects the CNS o other parts of the body. The peripheral nervous system may be either autonomic that control the unconscious activities or somatic that control the conscious activities.
Spinal nerves carry the information between spinal cord and body. These neurons are involved in somatosensory information. The divisions of 31 spinal nerves in human body is;
- cervical nerves; 8
- Thoracic nerves; 12
- Lumbar nerves; 5
- Sacral nerves; 5
- Coccygeal nerves; 1
The dorsal and ventral roots connects the spinal nerves to spinal cord and these nerves are formed from combination of nerve fibres. There is an opening between adjacent vertebrae from which spinal nerves originate except the one pair which originate from occipital and atlas bone.
