Question

Lions:
1. How many types of gametes will each parent produce?
2. What is the phenotype of a heterozygous four o'clock flower?
3. What are the possible phenotypes of the offspring from the cross
parental plants?
4. What are the possible genotypes of the offspring?
5. What is the percentage of the offspring to be red?
6. What would be the ratio of their offspring?
REMEMBER​

Answer 1

Answer:

There are two types of gametes will each parent produce and that is either recessive or dominant. 2.In the case of a heterozygous 4 o'clock flower, instead of having a red color because red is a dominant trait, it will be pink in color.

Answer 2

Answer:

3. The phenotype from the cross of the parental plants is -

•  Pink flowers and  red flowers.

• Red flowers, white flowers and pink flowers.

4. Genotype is also used to refer to the pair of alleles present at a single locus. with alleles "A" and "a" there are three possible genotypes AA, Aa and aa.

• three alleles 1,2,3 there are six possible genotypes - 11, 12, 13, 22, 23, 33. first we must appreciate that genes do not act in isolation.

5. The Rr genotype gives red flower colour. this happens in two combinations : 2(1/2*1/2)=1/2. so far,3/4 of the offspring have red flowers.

6. The number of times a genotype would appear in the offspring after a test cross. for example- a test cross between two organisms with the same genotype,Rr, for a heterozygous dominant trait will result in offspring with genotypes. RR, Rr and rr. in this example the predicted genotypic ratio is 1:2:1.
