Answer:
The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).

Answer:
The hemolytic anemia is a disorder in which the destruction of the RBCs is faster than their production of the RBCs. Hemolysis is the term used for the destruction of the RBCs.
The body of an individual produces antibodies if it senses or there is an antigen that is foreign to the body that helps in the destruction or removal of the particular antigen with the help of antibodies or B cells.
Rh(D) antigen is foreign to the Rh-negative woman as her RBCs surface lack the D antigen so if RBCs expressed to mother blood, IgG production begins and travels to the fetus through the placenta and start destroying RBCs of the fetus. Hemolysis of fetus results in hemolytic anemia and some times death of the baby.
