When two loci are on the same chromosome the phenotypes of the progeny sometimes do not fit the phenotypes predicted?

The same reason that dice don't always roll numbers as expected. Random chance. genetic propagation of traits is much more complex and therefor even less predictable than dice.

How do germ-cells make a single set of genes from the normal two copies that all other cells in the body have?
If progeny plants inherited a single whole gene set from each parent, then the aw of independent assortment would not work. this is because two different characteristics would be linked to each other and cannot be independently inherited. This is explained by the fact that each gene set is present not as a single long thread of DNA, but as separate independent pieces, each called a chromosome. Thus, each cell will have two copies of chromosome, one each from male and female parents. Each germ cell will take one chromosome from each pair and these may be either of maternal or paternal origin. When two germ cells combine, they will restore the normal number of chromosomes in the progeny, ensuring the stability of the DNA of the species.
Why is it necessary for meiosis to produces cells with fewer chromosomes?
If it did not, the chromosome number would double in each generation.
Difference in dihaploids and double haploids?
Haploid genomes contain a single copy of each chromosome while diploid genomes have two homologous copies. Usually organisms with a diploid genome inherit one chromosome of the pair from each parent. Double haploid occurs by doubling of the haploid genome resulting in pairs of chromosomes that are identical, so homozygous at each locus. This can be created artifically by using colchicine, which prevents microtubule polymerisation and therefore chromosome separation at meiosis where the chromosome number would be halved. This procedure is useful during plant breeding because of the homozygous plants produced.
P1 parents and the F1 progeny are all 24cm tall The F1s self fertilize and the F2 progeny vary in height from 12 to 36cm What is the mode of inheritance?

How b cell responds to the initial antigen challenge?

Do each set of chromosome define a character?
a set chromosome define about progeny which could be male or female
What is plural of progeny?

When was Dark Progeny created?

What is the duration of Progeny film?
The duration of Progeny - film - is 1.63 hours.
What is the plural form of progeny?
Progeny is used in both the singular or plural.
What events define telophase?
During telophase one, homologous chromosome pairs complete their migration to the two poles. A nuclear envelope reforms around each chromosome set and cytokinesis begins. Cytokinesis results in two progeny cells equipped with a set of replicated chromosomes. After this cycle, many cells proceed to prophase two.
When was Progeny - film - created?
Progeny - film - was created on 1999-03-30.
