The correct option to the punnet square illustrated in the image is 100% green (option C).
What is a punnet square?A punnet square in genetics is a graphical representation used to determine the probability of an offspring expressing a particular genotype.
A punnet square makes use of the alleles of gametes to deduce the genotype of the offsprings that will be produced from a cross.
According to this question, a homozygous green pea plant is mixed with a homozygous yellow pea plant. The punnet square is shown in the attached image.
The allele for the green pea is G while the allele for the yellow pea is g. G is said to be dominant over g (recessive), which means that in a heterozygous condition i.e. Gg, the green trait will be observed phenotypically.
If GG and gg genotypes are crossed, all of the offsprings will possess a Gg genotype, hence, 100% of the offsprings will be green.

Answers
The prevalence of this allele in the community is around 2% of the U.S. population.
Using Hardy-Weinberg equilibrium,
q2 = 1 ÷ 10,000 = 0.0001
q = √0.0001 = 0.01
p = 1 − q = 1 − 0.01 = 0.99
The carriers are heterozygous. Therefore, 2pq = 2 (0.99 × 0.01) = 0.0198 = 1.98%
According to the Hardy-Weinberg equilibrium, genetic diversity in a population will remain constant throughout time in the absence of disruptive factors.
By adding appropriate the alleles & dividing them by the number of alleles analyzed, we may get the values of p & q in a reasonable sample of people from a community.

. enhancers can influence the transcription of genes far away on the same chromosome. how are the effects of enhancers restricted so that they do not exert inappropriate transcriptional activation of non-target genes?
Answers
The creation of chromosome loops, which limit the engagement of the enhancers to just the genes inside the same loop, prevents enhancers from unintentionally triggering the transcription of surrounding genes since they act distantly from their target gene.
How are transcription promoters regulated?Enhancers are bound by sequence-specific transcription factors, which in turn make it easier for chromatin remodeling enzymes, histone modifying enzymes, and other co-factors to bind cooperatively, leading to the binding of the RNA polymerase II complex (RNA pol II).

For eukaryotes to produce the next generation through sexual reproduction, two cells must contribute genetic material.
Sexual reproduction, the process through which two individuals of different sexes combine their genetic information to create new species. In the majority of organisms, reproductive cells called gametes, which mate to create a diploid zygote, have chromosomes in their nuclei that carry the genetic material. The zygote grows into a new person. The most common method of reproduction among living things is sexual reproduction.
