Heritability is defined as Question 4 options: an interdisciplinary field of study concerned with the genetic bases of individual differences in behavior and personality. a process in which individuals with genetically influenced traits that are adaptive in a particular environment tend to survive and reproduce. a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group. a statistical estimate of the proportion of the total variance in some trait that is attributable to environment.

a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group.

Explanation:

The correct answer is a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group be auseHeritability is a statistical method use in the field of breeding and genetics that measure the degree or how much there is variation in observable traits or phenotypic traits in a population which is as a result in differences in genetic trait of different individual in the population.

b is dominant over the allele for the white fur.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
