Answer:b) Caenorhabditis

Explanation:

The C.elgans is a species of Caenorhabditis. It is a namatode which can be male or hermaphrodite. It lays 1000 of eggs which can be used for the purpose of research studies. These worms share common genes and molecular pathways like in humans.

Many of the genes present in C. elegans have functional counterparts as that of humans which makes them useful for determining the cause of human diseases. The mutant forms of genes of C.elegans can be used for screening the thousands of drugs. The genes have been used to determine the effects of ageing in humans, cancer, diabetes and other diseases.

Due to above reasons the C.elegans are considered as model organisms.

In a certain plant, fruit color is affected by an epistatic interaction between two genes. The fruit is red in the presence of a
sukhopar [10]

Answer:

15/16 or 93.75%

Explanation:

<em>The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.</em>

Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.

AaBb   x   AaBb

Progeny' Genotype       Phenotype

1 AABB                               red

2 AABb                               red

2 AaBB                                red

4 AaBb                                 red

1 AAbb                                 red

2 Aabb                                  red

1 aaBB                                  red

2 aaBb                                  red

1 aabb                                   white

Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.
