What fraction of offspring of the cross AaBb × AaBb would be homozygous for both the dominant alleles, assuming that they are on
Veseljchak [2.6K]

Answer:

A. 1/16

Explanation:

If we break the dihybrid cross of AaBb X AaBb into individual monohybrid crosses:

Aa X Aa :

     A    a

A  AA Aa

a  Aa   aa

1/4 of the progeny will be homozygous for dominant allele (AA)

Similarly, in cross Bb X Bb 1/4 of the progeny will be homozygous for dominant allele (BB)

Hence, in cross AaBb X AaBb:

1/4 * 1/4 = 1/16 will be homozygous for both the dominant alleles.

How will hurricane risks and impacts change over the next 100 years?
Papessa [141]

Answer:

Hurricanes will become more frequent and expand to new areas.

Explanation:

Global warming will rise sea temperatures worldwide. This means conditions for hurricanes will be met more often (they only form in higher than average sea temperatures). That means more hurricanes will form in the future. Also because of rising sea temperatures new areas will be effected by hurricanes as they will meet the threshold required for hurricanes to form.
