Attached earlobes are recessive to free earlobes. What genotypic ratio is expected when an individual with attached earlobes mat
Marianna [84]

Answer:

C

Explanation:

This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).

N.B: let F represent the gene involved.

A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.

A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.

The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff

The resulting four offsprings will

be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1

Choose the best location for obtaining a red bone marrow sample from a patient. 14) A) medullary cavity of femur C) hip bone B)
AnnZ [28]

Answer:

the hip bone

Explanation:

The bone marrow is divided into two; yellow and red bone marrow. The yellow bone marrow stores fats and contains mesenchymal stem cells which can develop into muscle cells or cartilage. The yellow marrow is located at the central cavities of long bones while the red bone marrow is located at the hip, sternum and humerus.

For a red bone marrow biopsy and aspiration to be done on a patient, the samples should be best obtained from the hip bone because it is a flat bone with soft tissues and no major organs and blood vessels are located.
