Answer:
A (one allele from each parent)
Explanation:
According to Mendel's experiments, an organism receives two forms of a gene called allele, one from each parent. He discovered in his law governing heredity that an organism will undergo meiosis and each of its gene variant (allele) will get separated into gametes (law of segregation). These gametes randomly combine when mated to yield two alleles in each offspring i.e. one from the male parent and one from the female parent.
He crossed pea plants in his experiment to observe the height trait. He crossed purebreeding pea plants that are homozygous dominant (Tall, TT) and recessive (short, tt). He realized that the F1 offsprings possess two alleles that is a combination of both alleles from the parent i.e. Tt.
He also realized that all the F1 offsprings are tall, which brought about his law of dominance, which says that an allele is capable of masking the expression of another in a heterozygous state. The allele that masks is called DOMINANT allele while the allele that is masked or covered up is RECESSIVE allele.
Hence, the F1 offsprings received a dominant allele (T) and recessive allele (t) from each parent to make up their genotype.
Answer:
Almost all of the cells in your body share the same DNA so false deku here! :3
Explanation:
Because Theyr lungs don’t get enough air they are supposed to
Typically, higher order streams contain MORE water than lower order streams.
Stream ordering is a mean of classifying natural channels in a water shed based on their sizes. The first order stream is the smallest stream and the second order stream is bigger than the first. Thus, the amount of water in the first order stream will be less that that of second order.<span />
Explanation:
Cortisol secretion is regulated by the hypothalamic hormone, CRH, and the pituitary hormone, ACTH, in the hypothalamus-pituitary-adrenal axis. Cortisol is known as a stress hormone involved in the response to physical and/or emotional stress.
