ANATOMY

Detailed explanation-1: -To obtain desirable genotypes, it is important to overcome the negative correlation between the traits. Index selection is a tool for improving traits simultaneously when a negative correlation exists between the traits.

Detailed explanation-2: -The way in which traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.

Detailed explanation-3: -Single-gene traits include some of the most observable physical traits in humans, like eye color, widow’s peak hairline, earlobe type (attached versus detached), presence of freckles or dimples, or the ability to roll your tongue.

Detailed explanation-4: -Inherited Traits in Animals Animals also inherit traits from their parents. Some common inherited characteristics are fur color, fur length, eye color, height, length of tail, ear shape, and patterns such as spots, stripes, or patches.
