Heredity increases diversity because when we inherit traits from our parents, we become a mix of both. Then, when we have children, they will inherit some of our traits and some of the other parent's traits. That increases diversity because different people get mixed together and create a new kind of person.

A compound that prevents the separation of the homologous chromosomes in anaphase I is being studied. Which of the following que
Virty [35]

Answer:

The correct answer is "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?"

Explanation:

A compound that prevents the separation of the homologous chromosomes in anaphase I is of great interest since it will cause cell cycle arrest, an effect that is looked in anti-cancer drugs. However, a throughout study of the compound must be done before it could be used for clinical trials. One of the questions that could be answered in this study is: "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?". The answer of this question will let us know if the cells will go to apoptosis, which is what we look for in an anti-cancer drug.

In peas, yellow seeds (Y) are dominant over green seeds (y). If a yy plant is crossed with a YY plant, what ratio of plants in t
LenKa [72]

The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.

Explanation:

Given that:

Dominant trait is Y (yellow seed color)

recessive trait is y (green seeds color)

cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.

Punnet square shows that:

    Y      Y

y   Yy    Yy

y   Yy     Yy

All the plants produced will be tall phenotype.

The yellow seed plant plants will be heterozygous i.e Yy

the phenotype ratio is 4:0

The genotype ratio is 4:0

The genotype of the offspring is Yy

phenotype is yellow colored seed plant.
