In pea plants, yellow seed is dominant over green seed. Construct a Punnett Square for the cross between a he)¿terozygous and a hom)=ozygous recessive (for this trait) Show all of the steps according to the instructions you have been given. Give the genotype and phenotype ratios resulting PLEASE HELP

genotype: 50% Yy 50% yy

phenotype: 50% yellow and 50% green

Explanation:

simply make a punnett square and cross the heter0zygous (Yy) and hom0zygous recessive (yy) between each other to get the genotypical results of Yy, yy, Yy, and yy. the phenotypical results are based on which color is dominant over which so Yy would be considered the dominant trait and that is yellow and yy is recessive and green. because you have two of each it is a 50% chance the pea plants offspring will be green and a 50% chance it will be yellow.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
