The correct answer is:

A. independent assortment

Explanation:

This Principle of Independent Assortment illustrates how different genes individually separate from one another during reproductive cells develop. Independent assortment of genes and their comparable traits was first mentioned by Gregor Mendel in 1865 during his education of genetics in pea plants.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

<em>Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.</em>

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

To measure the population of lake trout in a 250-hectare lake, 400 individual trout were netted and marked with a fin clip, then

kenny6666 [7]

Answer:

Estimated size is 1600

Explanation:

Given data:

Size of lake is 250 hectares

Total number of trout who netted is 400

Total number of trout in next week is 200

Total number of trout having fin clip 50

estimation population size is estimated by mark rupture as follow

Estimated population size $= \frac{(marked\ initally \times total\ recaptured)}{mark\ recaptured}$

Estimated size $= \frac{400\times 200)}{50}$

Estimated size is 1600

Radiation can cause breaks in human chromosomes. However, insects can survive much higher lecels of exposure. Why?

galben [10]

Explanation:

The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .

As the target of the radiation is the DNA .

Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
