Dennis_Churaev [7]3 years ago
4 0

Answer:

The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample.

Explanation:

A telescope mirror can be made from glass that is somewhat less pure than that used to make a lens, since light does not pass through it.

What is the expected phenotype of F1 progeny from a cross between two homozygous recessive mutants disrupted in different genese
LenaWriter [7]

Answer:

The correct answer would be - wildtype.

Explanation:

Let assume there are four genes which are :

A-B-C-D

In mutant first, the genotype would be:---a-b-C-D

In the mutant second, the genotype would be:--A-B-c-d

If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.

Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first.  This is possible only due to different genes are present in mutants.

Thus, the correct answer is - The correct answer would be - wildtype.
