N horses, the hair color gene has a dominant allele B (Black) and a recessive allele b (Chestnut). The gait gene has a dominant allele T (Trotter), and a recessive allele t (Pacer). If a Black Trotter is heterozygous for both traits, how many types of allele combinations for these 2 traits can be found in the gametes it produces

Four (4). BT, Bt, bT and bt

Explanation:

The hair color has two alleles, dominant B for black and recessive b for chestnut.

The gait also has two alleles, dominant T for trotter and recessive t for pacer.

Heterozygous black trotter will have the genotype BbTt.

Gametes usually have half the amount of allele of the parents

BbTt can have the the following allelic combination in its gamete: BT, Bt, bT and bt.

Hence, there are four (4) possible types of allele combinations for the two traits and they are BT, Bt, bT and bt.

You can see the attached image for the Punnet square analysis of the gametic alleles.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
