This is all about dominant and recessive genes. According to the picture it looks like the yellow flowers have the dominant genes YY and the green flowers the recessive yy. You breeded the YY with the yy to get Yy.  Now you have a plant with the dominant and recessive gene. The green flowers are  recessive so if you breed 'y'  with anything you get yellow flowers whether they only have the'Y' gene or the both 'Y' and 'y'.

Ecosystem- A community of living organisms  called producers, conumers, decomposers. Example: Plants (Producers) Rabbits (Consumers) Worms (Decomposers)
Community- Interacting group of various species Example: A forest of trees inhabited by animals.
Population- Traits of a group of plants and animals Example: 4 rabbits have broenn fur and 2 have black fur in a group.

Speculate on what science might be like without recognizable patterns in nature.
Sophie [7]
If there were no patterns in nature everything would be complicated. Atoms and all the little things would be different meaning our body structures would be different and the plants would be different too.

!!Help!! In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f
tatiyna

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.
