A major study has shed new light on the dim layer of the ocean called the "twilight zone" -- where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.

A scientist has an uncharacterized pea plant. She wants to determine the plant’s genotype for seed color. In order to be certain

Answer:

Recessive phenotype plant

Explanation:

If the plant has recessive genotype then it will be easy to identify because it will have the recessive phenotype. However if the plant has dominant phenotype it can either have homozygous genotype or heterozygous genotype. To confirm if the plant is homozygous or heterozygous, a test cross can be done with plant having recessive phenotype.

If our test plant is homozygous dominant, it will pass one dominant allele to the next generation and all the offspring would have dominant phenotype. If our test plant is heterozygous dominant it will pass one dominant allele to half of the offspring and one recessive allele to another half so 50% of next generation will have dominant phenotype and other 50% will have recessive phenotype.

Hence by test cross (cross with recessive phenotype plant) it is possible to determine the genotype of the uncharacterized pea plant.

Serjik [45]

Answer:

B. Granulocyte

Explanation:

Granulocyte is the type of white blood cell with fragments in its cytoplasm. These fragments usually help in the digesting the cells of the foreign body(pathogenic organisms).

There are three main types of Granulocytes which are known as the Neutrophils, eosinophils, and basophils. They all perform variety of functions ranging from phagocytosis to cell lysis of foreign bodies.

The diagram represents a dihybrid cross between two pea plants heterozygous for both seed color and seed shape. mc021-1.jpg What

bija089 [108]

The correct answer is 9:3:3:1

When two homozygotes for two traits cross, the phenotypic ratio of the offspring is 9:3:3:1 ( unless other factors like epistatic interaction change the inheritance model).
In our case, we have two simple traits of seed color and seed shape that follow the Mendelian model of inheritance.

In this dihybrid cross, we have
9/16 of the offspring expressing both dominant traits ( yellow and round seeds)
3/16 expressing one dominant and one recessive trait ( yellow and wrinkled)
3/16 expressing the other dominant and recessive trait (green and round)
1/16 expressing both recessive traits ( green and wrinkled)
