What advantage does hermaphroditism have for slow-moving organisms such as the earthworm

1 answer:

8 0

When an organism is sessile, or slow moving it might be very hard for that organism to find food, shelter and a reproductive mate.
One of many solutions to the problem of finding a mate is hermaphroditism.
When an organism is hermaphroditic it means that it has the reproductive organs of both sexes and that it is able to self-fertilize.
This solution, although sometimes very useful, if used all the time can lead to inbreeding and have negative effects on the genetic diversity of the population. Therefore, hermaphroditic organisms self-fertilize only in cases where there is no available mate to be found.

How do sheet joints and exfoliation domes form in granite plutons?

fomenos

<span>Sheet fractures are accurate fractures defining slabs of rock that range from 0.5 to 10 meters thick. They normally form in sets parallel to the Earth's surface but may form in convex-upward or concave-upward sets. The most popular hypothesis of the formation of sheet fractures is that they are the result of expansion and tangential fracturing consequent on erosion offloading or pressure release.</span>

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)

vodka [1.7K]

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

The likelihood of each possible offspring phenotype is:

Orange petals with tall stem and orange petals with small stems present in ratio 12:4 i.e. 3:1.
