Answer:
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an as phenotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
Explanation:
One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (SS) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the phenotype of the parents must be considered. If one parent is heterogeneous (SS) and the other is homologous recessive (SS), then half of their offspring will have a smooth chin
Cells differentiate in the womb.
Answer:
new moon and full moon
Explanation:
Tides occur due to gravitational force of the sun and the moon. During New moon and Full moon, the Sun and the Moon are aligned in a straight line. This alignment leads to strong effect of gravity on tides and highest high tides and lowest low tides occur. These tides are referred as spring tides.
Neap tides occur when the sun and the moon are aligned at right angles. Effect of gravity is minimum and low tidal range is observed.
Answer:
X chromosome
Explanation:
the gene for albinism is located on an X chromosome. Females have two X chromosomes, while males have one X chromosome and one Y chromosome. X-linked ocular albinism appears almost exclusively in males
