Introduction:

The genetic makeup of an organism is termed as the genotype. It describes a complete set of genes of an organism.

Summary Introduction

c.

To determine:

Whether the B and D loci are linked or assort independently.

Introduction:

According to Gregor Mendel’s law of independent assortment, when two or more traits are inherited, the alleles for separate traits are transmitted to the next generation independent of each other. The assortment of one allele does not affect the selection of the other trait. When two genes are linked, they tend to be inherited together. When two genes are located on the same chromosome or occur very close to each other are said to be linked.

n corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of the corn plants (i.e the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male sterile lines Using the cardboard chips, simulate the crosses indicated below. Give the genotypes and phenotypes of the offsprings in each cross, and properly label the nucleus and the cytoplasm each individual in the cross Legend male sterile cytoplasm Male fertile cytoplasm FF nucleus Ff nucleus ff nucleus A.
