the answer to your question is 1 1/8
If the lower case letter indicates the recessive gene, then there is 0% chance of someone with genotype ee to have a dominant, detached earlobe, appearance
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.
Connective tissue.
- tissue that provides structure, support, and protection to other human tissues and organs. In addition to helping to transport nutrients and other substances between tissues and organs, connective tissue also helps to store fat and mend damaged tissue. A gel-like substance, fibers, and cells make up connective tissue.
- connective tissue is a set of tissues found throughout the body that help to keep the body and its organs in shape as well as to give internal cohesion and support. The more specialized and recognized variations—bone, ligaments, tendons, cartilage, and adipose (fat) tissue—as well as a variety of fibrous tissue types that differ only in density and cellularity are included in the connective tissues.
- The majority of the organs in the abdominal cavity are connected to the abdominal wall by a membrane strip called the mesentery.
Therefore, the correct answer is connective tissue.
