Oxpecker birds eat parasitic ticks off the backs of zebras is an example of mutualism.
Mutualism is defined as a relationship between organisms in which both the individuals involved are benefitted from each other.
In the case of oxpecker birds and zebras, the oxpecker birds benefit as they get their food from the parasitic ticks living on the zebra and the zebras benefit as the birds help them to get rid of the parasites.
In this way, both these organisms are involved in a mutualistic relationship.

Hitchhiker's thumb (H) is dominant to no hitchhiker's thumb (h). A woman who does not have hitchhiker's thumb marries a man who

kakasveta [241]

Answer:

Genotypic ratio of offsprings will be: 1 (Hh) : 1 (hh)

Explanation:

This question involves a single gene coding for the possession or not of Hitchhiker's thumb in humans. The allele that codes for Hitchhiker's thumb (H) is dominant over the allele for no hitchhiker's thumb (h).

Based on this question, if woman who does not have hitchhiker's thumb (hh) marries a man who is heterozygous for hitchhiker's thumb (Hh) i.e. hh × Hh, the following gametes will be produced by each parent:

hh - h and h

Hh - H and h

Using these gametes in a punnet square (see attached image), the offsprings with the following genotypic ratio will be likely produced:

1 (Hh) : 1 (hh)

N.B:

- Two (2) of them were Hh i.e. with Hitchhiker's thumb

- The other two were hh i.e. no hitchhiker's thumb.
