4. suppose that a dominant allele (p) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. if two heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring?

The correct answer would be:

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
