The process of separation of homologous chromosomes is during meiosis is referred to as disjunction. gametogenesis is production of gametes and it occurs in sex cells. disjunction occur during anaphase of meoisis I and in humans it results in separation of homologous chromosomes into two sets each containing 23 chromosomes. these chromosomes will eventually move to the opposite poles of the cell.
Answer:
Originally called 'Mintonette', the game of volleyball was invented in 1895 by William G Morgan, in Holyoke, Massachusetts at a YMCA. ... It was because of his role that Morgan had the opportunity to direct numerous programmes, exercises and sports classes for male adults.
Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available
Therefore
Total genetic variance (VG) = VA + VD
= 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
= 100
Recall,
Selection response is heritability multiplied by selection differential.
That is
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30
= 430 Units
