Answer: a. True

Explanation: Through evolutionary time, animals have developed more-complex body plans, including  true tissues, non-segmentation and bilateral symmetry which is possible as a result of evolutionary innovation--the introduction and progression of novel traits compared to what exists before leading to a more advanced or complex form. Non-segmentation indeed allows for evolutionary innovation in body form.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p
vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt   x   tt

Offspring = Tt   Tt   tt   tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt   x   tt

Offspring = Tt   Tt   tt   tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

A particular ant species has four pairs of chromosomes. Identify the genetic possibilities from independent assortment of a game
pantera1 [17]
In this question, the ant has 4 pairs of chromosomes. Each pair of chromosomes will be separated in a gamete, resulting 4 unpaired chromosomes. That is why gamete is called haploid or n.
That means only 1 of the 2 chromosomes that will be carried into a gamete, assuming the gene heterozygote then there would be 2 possibilities. Since each chromosome pairs can produce 2 possibilities for each male or female, their interaction will result as (2x2) 4 possibilities.
Then for 4 chromosomes would be 4^4 possibilities= 256 possibilities of offspring

I hope this helped
