Consider the results of a testcross performed on an organism heterozygous for 2 genes. For each scenario of gene arrangement for the two genes, write the percentage of nonrecombinant and recombinant progeny that will result from the testcross. Gene arrangement of 2 genes % Nonrecombinant progeny % Recombinant progeny
Unlinked (independently assorting)
Completely linked genes (with no crossing over)
Linked genes (with some crossing over)

Following are the answer to the given points:

Explanation:

Mendel had established some essential concepts concerning inherited mechanisms such as the patterns of transmission of genes to offspring depending on their chromosomal placements. This same notion of linkage was offered to describe the pattern of the legacy of alleles on its chromosomal position.

Two different chromosomes have specific isoforms – for example, A and B which have two different features. As just a result, 50 percent of gametes are parental throughout type AB, and the other 50 percent of a recombinant in zygotes are quasi (aB & Ab) and 50 percent of the progenies that outcome from this mixture of gametes, therefore, are nonrecombinant in 50% and the cloned in 50 percent of the genetic makeup AaBb.

With two fully linked genes, e.g they exist on the very same chromosome and no cross-over occurs, all gametes are similar to parent types (AB and ab), like they do not split themself nor are diverse and culturally produced (nonrecombinants).

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above
