Answer:
a. The allele for round seeds is dominant to the allele for wrinkled seeds.
Explanation:
Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.
A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
Answer:
B. Muscle
Explanation:
During embryonic development, three germ layers start to form in order to eventually go through the process of differentiation. These three layers are: the ectoderm - <em>outer layer</em> -, the <u>mesoderm</u> - <em>middle layer</em> -, and the endoderm - <em>inner layer</em> -.
The <u>mesoderm gives rise to the both skeletal and smooth muscles</u>, <u>blood vessels, heart muscle, cartilage and joints, bone, cartilage, joints, connective tissue, blood cells</u>, amongst other tissues.
