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.

How are muscles the contractile specialists of the body?
Mariana [72]
<span>Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.</span>
