Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
No , it didn't increase cases of addiction.
Answer:
The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1 and phenotype proportion 3:1
Explanation:
The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.
For the characteristic "seed color" the green color would be G and yellow represented as g.
At the cross of two heterozygous squashs:
- Parents: Gg X Gg
- <u>Punnett's Square</u>:
Alleles G g
G GG Gg
g Gg gg
Offspring:
- A pumpkin of green seeds GG (25%)
- Two pumpkins of green heterozygous seeds Gg (50%)
- One pumpkin of yellow seeds gg (25%)
Genotype proportion 1:2:1
Phenotype proportion 3:1
