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

ea plant and a short pea plant produces 43 tall offspring and 47 short offspring. If one of the tall offspring is crossed with one of the short offspring, what ratio of genotypes would be most likely in their offspring

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

Answer:

the ratio will be in equal proportion of  1:1

Explanation:

assuming  that  dominant  TT  is crossed below with recessive short stalk( tt).

the F1 is    Tt, Tt, Tt, Tt.

if one of the heterozygote dominant(Tt) is crossed with the(homozygote recessive)  tt.

Then in F2

Tt, Tt= 2 ; tt, tt,=2

<u>2:2  is  formed, </u>which equals 1(Tt):1(tt) when cut through to simplest whole number.

kvv77 [185]

Answer:

The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.

Explanation:

Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.

What type of muscle assists an agonist by causing a like movement or by stabilizing a joint over which an agonist acts? a synerg
ser-zykov [4K]

Answer:

The correct answer will be option-a synergist

Explanation:

In the musculoskeletal system, the muscles to produce a movement work in group or pairs like hamstrings and quadriceps or biceps or triceps.  The muscles which work is known as an agonist or prime mover.

The muscle which helps prime mover by moving in the same direction and at the same time is known as synergists. The synergists produce a similar motion as the prime mover and also stabilizes the joints which hold the position for smooth movement of agonist.

Thus, synergist is the correct answer.

You want to test which size of soccer (football) ball is easiest to juggle with your feet. You test a size 3, size 4 and a size
Semenov [28]

Answer:

<u>independent variable:</u> size of soccer ball

<u>dependent variable</u>: period of time the balls stay in the air

<u>control variable</u>: parts of the body used to juggle the ball

Explanation:

The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.

The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.

The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.

Hence, in the illustration;

<u>independent variable</u>: size of soccer ball

<u>dependent variable</u>: period of time the balls stay in the air

<u>control variable</u>: parts of the body used to juggle the ball
