<span>For a species with four pairs of chromosomes, 16 gametic combinations are possible</span>
If a species has 4 pairs of chromosomes will mean that the species has 8 alleles. In mating, only one of the pair will be inherited. In this case, the probability of the combination will be 2^4 assuming all the genes is heterozygote.

Simply, transcription is a copy of __________
WITCHER [35]

Answer:

b. mRNA from DNA

Explanation:

Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.

The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.

The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.

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.
