Someone help me with this
nadya68 [22]
A horseshoe crab has been around for almost 500 million years. They are classified as arthropods and not actual crabs. However, There are many reasons that have helped them survive this long including, they can eat almost any organic matter. There blood is different from normal, in fact it’s blue. This blood helps them heal any wounds right away. They can also live in areas with very low levels of oxygen, meaning habitat is not a big issue for them. Evolution has also helped them grow and adapt seeing as they’ve survived this long.

Hope that helps:)

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produce
FinnZ [79.3K]

Answer:

C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.

Explanation:

The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.

The heterozygous plant  Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).

  • Dr: parental
  • dR: parental
  • DR: recombinant
  • dr: recombinant

To calculate the frequency of each type of gamete, we must use the formula:

Distance (map units) / 100 = frequency of recombination.

18 mu / 100 = 0.18.

The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.

The frequency of parental gametes will be:

1 - frequency of recombinant gametes

1 - 0.18 = 0.82

But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
