B. A gamete carries one allele for a gene.
C. A gamete can carry multiple alleles for a trait.
D. Some gametes are dominant and some are recessive.
The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.
Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.
Answer: The correct answer is- B. A gamete carries one allele for a gene.
Gamete ( also called sex cell or reproductive cell) is a haploid cell ( having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to Mendel's second law of inheritance that is law of segregation,
For every trait/ characteristic of an individual, there are two variant forms of a gene (called alleles) that are separated from one another so that every gamete possesses one allele. This law is also known as law of purity of gametes.
Thus, option B) is the right answer.
Answer: A. Julie loves chicken noodle soup, but her cold is making it taste bland.
Sensory interaction is the interaction among various sense organs of the body. It depicts how one sense organ influence the response from other sense organ. Taste and smell are examples of senses which are dependent on each other and can influence the response generated by external stimuli. For example, food tastes are bland when a person is not able to inhale it's smell. Julie loves chicken noodle soup, but her cold is making it taste bland. Here, the taste of noodle depends upon smell of food as, Julie is not able to inhale the smell of food therefore, the taste is bland. Hence, this illustrates the best example for sensory interaction.
Answer:
A is a eukaryotic cell while B is a prokaryotic cell
Explanation:
The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.
In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.
Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.
