what would the likely result be if a child receives a dominant gene for tallness from one parent and a recessive gine for shortness from the other parent
If a child receives a dominant gene for tallness from one parent and a recessive gene for shortness from the other parent, the likely result would be that the child will exhibit the dominant trait for tallness. This is because dominant genes override recessive genes in terms of phenotype expression.
If a child receives a dominant gene for tallness from one parent and a recessive gene for shortness from the other parent, the likely result would be that the child would exhibit the dominant trait for tallness. This is because the dominant gene for tallness is expressed over the recessive gene for shortness.
To further explain, genes come in pairs, with one gene inherited from each parent. Each gene can be either dominant or recessive. In this case, the dominant gene for tallness "dominates" the recessive gene for shortness.
The specific genes involved in determining height can be represented by the letters "T" for tallness (dominant gene) and "t" for shortness (recessive gene).
The possible combinations of these genes from the parents are as follows:
Parent 1: Tt (one dominant gene for tallness and one recessive gene for shortness)
Parent 2: tt (both recessive genes for shortness)
When the genes are combined, the child would receive one gene from each parent, resulting in the following possibilities:
- Tt: The child has one dominant gene for tallness and one recessive gene for shortness. The dominant gene for tallness is expressed, so the child would likely be tall.
- tt: The child has both recessive genes for shortness. The recessive gene for shortness is expressed, so the child would likely be short.
Therefore, the likely result would be that the child inherits the dominant gene for tallness and is therefore tall.
