_____ is the irregular break of a mineral
Sati [7]

Answer:

I'm not sure if this is right, but i believe the right answer would be fracture.

Explanation:

In geology, a fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces. A fracture will sometimes form a deep fissure or crevice in the rock. Fractures are commonly caused by stress exceeding the rock strength, causing the rock to lose cohesion along its weakest plane.

hope this helps :)

Alleles of the gene that determines seed coat patterns in lentils can be organized in dominance series: marbled &gt; spotted = d
SSSSS [86.1K]

Answer:

a.The phenotypic proportions obtained after having the genotypes are 50% marbled seeds, 25% spotted and dotted seeds since they are codominant, 25% spotted seeds.

b. Taking into account the F1 genotypes in the previous point, the expected phenotypes for the first crossing are 100% marbled seeds and for the second crossing 100% dotted seeds.

Explanation:

Let's suppose:

Marbled allele: M

Spotted allele: S

Dotted allele: D

Allele for Clear: C

a. Because both crosses were between homozygous parents, the entire F1 genotype is the same.

For the first crossing the descendants have the MS genotype, and for the second crossing the descendants have the DC genotype. It is enough to make a Punnett square to obtain the different combinations of genotypes between the crossing of MS and DC.
