I think the answer to this is 2.
A meteroite is a meteor that struck earth
a meteorode is a small rock in space that could eventually turn into a meteor
asteroids are a cluster of meteors
comets are icy meteors, seeing that the oort cloud is mostly ice i would say that the answer is comets.
Answer:
The law of independent assortment states that the different genes get separated independently of each other and gets assorted into gametes to produce different combination of genes.
It was formulates by famous scientist G. Mendel based on his work on peas.
For example, in a traditional dihybrid cross of true breeding round and yellow seed plant with wrinkled and green seed plant, F2 generation show four different combinations of phenotype:
- round and yellow
- round and green
- wrinkled and yellow
- wrinkled and green
It shows that genes for round and yellow were independently inherited and genes for wrinkled and green were independently inherited. Else, new combinations could not be observed.
Homologous recombination is an event that takes place in prophase I during meiosis. The genetic material is exchanged between the non-sister chromtids of homologous chromosomes. It adds into the genetic variation within a population by producing more combination of genes in the gametes.
It does not violate the law of independent assortment as the genes were independently assorted. It only helps in producing more combinations of genes.
Answer:
Four
Explanation:
Let the allele for black fur be B (the alternate will be b), the allele for active behavior be A (the alternate will be a), and the allele for light eyes be L (the alternate will be l).
<em>Heterozygous dominant for black fur = Bb</em>
<em>Heterozygous dominant for active behavior = Aa</em>
<em>Homozygous recessive for light eyes = ll</em>
Hence, the genotype for a male that is heterozygous for the dominant traits of black fur and active behavior but is homozygous recessive for light eyes will be BbAall.
Bb Aa ll
Possible Gametes
<em>BAl, Bal, bAl, and bal</em>
Therefore, the number of different types of gametes produced by the male mouse is four.
