When a tapeworm steals nutrients from the gut of a mammalian host, that symbiosis is called?
Umnica [9.8K]
Tapeworms are known to feed off of their hosts to complete their life cycle. This type of symbiotic relationship is called parasitism. Parasitism is defined as the type of symbiotic relationship wherein only one of the two interacting organisms benefit, at the latter organism's expense. Parasites could either be found inside or outside the host's body. Tapeworms are internal parasites.

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant
mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.
