Answer: 2 haploid cells, 10 chromosomes each.

Explanation: meiosis produces haploid gametes from the parent cell.

Effectus [21]

1. If we cross YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits)

P:  YyLl  x  yyll

F1 generation: YyLl: 400 Yyll: 100 yyLl: 100 yyll: 400

Recombinant offspring are those children whose genes contain a non-parental allele combination  (neither allele group is directly inherited from either parent). This happens when genes are located on the same chromosome but are so far apart from one another so that their alleles get crossed over during meiosis. In this case, Yyll and yyLl are the recombinant.

2. Calculation of distance between Y and L.  

The numbers of the two recombinant types is 200 (100 Yyll + 100 yyLl) and 800 parental offspring.

Total number of offspring is 1000.

So: 200/1000*100=20 map units.

There is 20 percent recombinant offspring frequency.

Construct incomplete dominance vs codominance
Firlakuza [10]

Answer:

Codominance is when both alleles in the genotype are seen in the phenotype, like a flower that is half blue and half red. Incomplete dominance is a mixture of the alleles, like for example, a mixture of blue and red flower, a purple flower.

Information about common resources
Amiraneli [1.4K]
A common resource (or the "commons") is any scarce resource, such as water or pasture, that provides users with tangible benefits but which nobody in particular owns or has exclusive claim to. A major concern with common resources is overuse, especially when there are poor social-management systems in place to protect the core resource.
