In a dihybrid cross for round and yellow seeds (RrYy x RrYy), what is the probability of having green and wrinkled seeds?
Virty [35]

Answer:

The probability of having green and wrinkled seeds is equal to 6.25%

Explanation:

Here R allele is dominant over r allele and Y  allele is dominant over y allele.

Thus, a green phenotype will have genotype rr

and a wrinkled phenotype will have genotype yy

The punnet square representing the cross between RrYy  and  RrYy is as follows -

RY         Ry         rY         ry

RY RRYY RRYy RrYY RrYy

Ry RRYy RRyy RrYy Rryy

rY RrYY RrYy rrYY rrYy

ry RrYy Rryy rrYy         rryy

Out of all 16 offspring, only one offspring with genotype "rryy" represents green and wrinkled seeds.

Thus,  the probability of having green and wrinkled seeds is equal to

\frac{1}{16} * 100\\= 6.25%

What is the difference between a biomass pyramid and a pyramid of numbers
tamaranim1 [39]
A biomass pyramid shows the mass that each trophic level are producing overall. e.g., 10 000 kilograms of grass - 1000 cows - 100 kilograms of meat.
A pyramid of numbers shows how many animals in numbers are on each trophic level. E.g., 100 kookaburras - 20 snakes - 100 insects. A pyramid of numbers is not necessarily triangular in shape all the time.
