In the snail cepaea nemoralis, an autosomal allele causing a banded shell, u, is recessive to the allele for an unbanded shell,

u. genes at a different locus determine the background color of the shell. the allele for a yellow shell, b, is recessive to the allele for a brown shell,
b. a banded, yellow snail is crossed with a homozygous brown, unbanded snail. the f1 progeny are then crossed with banded, yellow snails in a testcross. predict the percentage of progeny in each phenotype if the two genes are linked with no recombination, if the two genes assort independently, and if the genes are 20 m.u. apart. place the percentage for each phenotype for each of the scenarios in the table below. percentages can be used more than once.

There will be no recombinant progeny in absolute linkage. The F1 inherted banded and yellow alleles (BBCY) together on one chromosome from the banded yellow parent and unbanded and brown allels (BOCBw) together on the homologous chromosome from the unbanded parent. All the F1 gametes will contain only these two allelic combinations, in equal proportions if there is no recombination. F2 cross progeny will have 1/2 banded, that is yellow and 1/2 unbanded brown.

This level of direct harvesting could cause the ecosystems to be severely damaged. The correct option among all the options that are given in the question is the second option or option "B". This type of fishing can disturb the natural balance and ultimately several species might vanish from our earth.

Heterozygous is another word for what?
tatyana61 [14]

Answer:

Heterojunction or having two identical alleles of the same gene.

Explanation:

A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials.
