A single pair of goldfish in a aquarium produced a large number of offspring.

Biology
1 answer:
kap26 [50]3 years ago
6 0

Answer:

C. Offspring were produced from different combinations of genes.

Explanation:

The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.

Population A consists of 100 hens that are fully isogenic and that are reared in a uniform environment. The average weight of th
qaws [65]

Answer:

a. the environmental variance (VE) = 3.5 g ²

b. 17.5 g ² for population

c. the heritability of broad sense (H2) = 0.83

Explanation:

a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²

b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²

We generate the following formula with the data obtained previously to find the genetic variation

VT = VE + VG

then VG = VT-VE

replacing data:

VG = 21.0 - 3.5 = 17.5 g ² for population

c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:

H2 = VG / VT = 17.5 / 21.0 = 0.83
