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.

Under what environmental conditions would a zygote not undergo meiosis
sashaice [31]

A zygote will not undergo meiosis in an environmental state that is not favorable for the zygote’s survival i.e. the chance of the zygote to survive is not certain. Take for example, chlamydomonas will form a zygote under normal asexual mitotic reproduction in a favorable environmental condition. However, under unfavorable environmental conditions the organism also reproduce sexually to form a zygote but will never proceed to meiotic division because of the unfavorable environmental state.
