Answer:
The question lacks options and the incomplete punnet square; the incomplete punnet square has been added as an attachment while these are the options:
A) All red flowers
B) All pink flowers
C) 1 red : 3 pink flowers
D) 3 red : 1 pink flowers
The answer is D
Explanation:
According to the question, the genotype of a plant that produces red flower phenotype is about to be determined. For this flower colour gene, two alleles are involved in which the red color (R) allele is dominant over the pink color (r) allele I.e. the R allele will mask the expression of r allele in a heterozygous state.
The red-flowered plant with unknown genotype was crossed with a heterozygous red-flowered plant (Rr). Since a red flowered plant can either be Rr (heterozygous) or RR (homozygous), we use the Rr plant in the punnet square. The unknown genotype, assuming it has a Rr genotype, will produce RR, Rr, Rr and rr offsprings when crossed with another heterozygote (Rr).
These offsprings show a 3 red : 1 pink phenotypic ratio, making option D a valid prediction.
R r
R RR Rr
r Rr rr
Answer:
They use his mind and pollination will not change to heterozygous
Animal cells do not have cell walls. So the answer is B.
A control group is going to be something that you don’t “experiment on or change. It is grown or watched under normal conditions. This way you have a medium to say how things are “supposed” to go.
The experimental group is going to be where you “experiment” and change the normal conditions to see what outcome will occur ( under different conditions then normal )
