A bat wing is homologous to a whale's: FLIPPER
No, it is not alive because water is a non-living thing. Aka it doesn't have cells or organs. The fact that it rolls up on the beach all depends on wind and the gravitational pull of the Earth.
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.
Answer: directional
Explanation:
Because only one trait was favored. When bears are cold, being bigger helps them better adapt to the coldness. Adjusting to the weather is one trait.
