Answer:

<h2>616 Short with white flower </h2><h2>1850 Tall with white flower </h2><h2>1850 Short with purple flower</h2>

Explanation:

A dihybrid cross is in which two genes of two different traits are crossed

As given, two dihybrid pea plants (tall with purple flower) are mated, resulting 5550 out of 9866 were tall with purple.

T= tall

t= short,

P= purple,

p= white;

So genotype of parents are TtPp ; T is dominant over t, P is dominant over p.

Crossing between two parens= TtPp × TtPp

so gamets are = parent 1: TP, Tp, tP, tp and parent 2: TP, Tp, tP, tp

Hence the four different gametes formed.

Now arrange the gametes on the top and left side of a Punnett square it'll genotypically results into different combinations, by which phenotypic ratios can be calculated.

offspring are = TTPP, TTPp, TtPP, TtPp....................TTpp, Ttpp.....ttPP, ttPp.......ttpp

(T_P_)= Tall with purple flower,

(T_pp)= tall with white flower,

(ttP_)= short with purple flower,

(ttpp)= short with white flower.

so it show 12:3:3:1 ratio'

Phenotypic classes are:

616 Short with white flower

1850 Tall with white flower

1850 Short with purple flower

3) What are Florida officials/ Biologists doing about the python problem?

MakcuM [25]

Answer:

Florida officials through the Lacey Act has banned the transportation of the pythons and many of them were killed too.

Explanation:

Some of the native Burmese pythons of South and South-East Asia were transported to the U.S.A as a rare species. Unaware of its large species and growth many people adopted them as pet. It led to a large breeding issue in Florida and now it has become a great threat to the biodiversity of Florida.

However, by the Lacey Act of Florida officials the transportation of the pythons were banned. They were trapped and killed too. But these methods however, have failed to decrease the population.
