Red-flowered snapdragons are crossed with white-flowered snapdragons, producing all pink snapdragons in the F1 generation. What
Nitella [24]

Answer:

Red (1/4), Pink (1/2), white (1/4)

Explanation:

This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).

The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.

Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.

RR offsprings (1/4)- Red flowered

RW offsprings (2/4 or 1/2)- Pink flowered

WW offsprings (1/4)- White flowered

Cerrena [4.2K]

Answer: In 2008, the population of New Zealand was approximately 4,275,000 people. If the birth rate was 14 births for every 1,000 people, approximately 59, 850 births occurred in New Zealand in 2008.

Explanation: For every 1,000 people, there are 14 births. So, for every 4,275,000 people, there will be 59,850 births. This can be worked out this;

1,000 people = 14 births

4,275,000 people = y birth

Cross multiply, you will get

1,000 people x y birth = 4,275,000 people x 14 births

Divide both sides by 1,000 people, you will get

y = (14 x 4,275,000) ÷ 1,000

y = 59,850,000 ÷ 1000

y = 59,850 births
